Brush strokes become jagged after a few seconds

Report · Apr 02, 2014

I've tried just about everything to narrow down and eliminate this problem, with no luck.

When I first start PS and paint a line with a simple hard round brush, it's nice and smooth. After about 15 seconds (or 4-5 lines), the lines become jagged.They're not pixely - it's more like what happens if you have smoothing turned off. The effect is more pronounced when I paint zoomed out, as if the input data is constrained to the zoomed out pixel size.

This is not a tablet problem - it happens with the mouse as well.

It does not happen with the lasso selection tool, so it seems limited to the brush tool.

Here's an image showing a series of brushstrokes, going from left to right. You can see how the stroke quality degrades from the first stroke (on the left) which is nice and smooth, to the strokes on the right which are jagged. You need to view the image at 100% to see what's happening clearly.

The fact that this problem doesn't appear when I first start the program, then creeps in, is really perplexing! Once it starts it never goes away.

Clip Studio is a new app on me, but it looks interesting. My normally pants connection is worse than ever this evening, and it is difficult researching things, so can you outline the difference between the $50 standard, and $220 EX versions? Which do you use?

What does your system look like. To tell you the truth I don't seem to be having any of the problems you are having with the mouse or Wacom pen. I don't like installing Plug-in I have no intention of using. Particulart Photoshop Plug-in for I keep plug-ins outside any Adobe folder and plug-installers a tend to install the plug-in in every version of Photoshop they find installed. I just download a trial of LN and after it installed I removed all the plug-in it installed into different version of Photoshop one my system. I copies the 32bit and 64Bit plug-ins into my Photoshop plug-ins trees. My windows workstation is good but not top of the line good. I do not see the jitter you seem to be getting with or without the plug-in enabled, I'm no artiest all I can do is scribble fast and slow, I do not see bad jitter. Here is what my system looks like and what I see when I scribble fast and slow.

I have the exact same issue. There is jitter, and even using Nezumi, hasn't fixed it.

What saddens me is that I am a huge fan of Adobe, yet nothing is being done about this. I use this product professionally, and believe me, it matters.

There are at least 2 more 'showstopper' bugs that I have found, unfortunately, I have Photoshop CS6, and I was told I'd have to upgrade to CC for support. Never mind, that CC at work has the same issues, and I don't want to spend another $800 just to see nothing done about it. These issues should be hotfixed - because it should have worked correctly to start with.

Report · Oct 23, 2014

This bug is extremely frustrating!

While working on Lazy Nezumi I have found some clues as to why this problem is happening.

I have sent my findings to Adobe and have offered to help them fix the issue but so far haven't had any answer.

Report · Apr 03, 2014

The question is, is there anything near the tablet and your stylus or mouse that may cause interference, like another monitor, or speakers or a TV, radio, etc. Try moving the position of your tablet. If it's happening after a few strokes regardless of where you are drawing, then maybe it's to do with something else like memory or scratch disk. Make sure to update your tablet drivers to the latest version too.

Peter, unfortunately the Wacom line jitter has been an ongoing issue for over a year, or maybe two years. The Wacom forums are full of unresolved posts about it. Most of thos posts seem to involve Macs, but I can testify that it happens with Windows as well.

Then there is the sticky brush issue where you can select other tools without tapping the stylus on the tablet to release the brush. I bought a new penn for my Intuos 4, and id a clean reinstall of Windows 7 Pro and all my apps with freshly downloaded drivers, and the sticky brush problem was still there from the get go.

Then there are all those poor folk who have paid serious money for big Cintiqs and have even worse line jitter. Wacom were putting out a new driver every month or so a year back, but seem to have given up now. Apparently these issue only happen in Photoshop, and wacom products work fine in other applications, so maybe there is a blame game going on.

All I know is that it a royal PITA and absolutely not good enough after such a long time.

Report · Jul 03, 2014

I have exactly the same symptoms on Intuos4 CS6 windows 7, typing this while I wait for 6.2 download

I too have bought LN in vain, and that's when I discovered that it had the delay effect on window switching because everytime I touch setting in LN the brushstroke was beautiful until a couple of strokes later

if this works for me I suspect the older wacom drivers have something which compensates for windows 7's mouse interpolation problems, because this particular kind of jiggle turns up in MS paint with a mouse as well (even if you use a ruler) minus the first few good strokes.

Report · Jul 03, 2014

FIXED!!!!!!

by rolling back my driver to 6.2.w5 (btw wacom Asia's site is easier to navigate for this sort of thing)

so relieved, I don't even care that I ended up buying a new stylus in the process. >.> I'll set them up with different pressure curves or something, the older one is rattly anyway, I need to get a back up.

so happy.

I have the same problem. it comes and goes as I work. and it's quite frustrating while working with fine lines.

the only way to make it go away for the time being is shift from PS to another app and switch back (it'll be gone for awhile).

I'm a professional illustrator, working on several machines with win7pro 64bit - HP Workstation Z420 with 32GB, asus HD7850 xeon etc. and HP EliteBook 8460p with 8GB ...

and I don't think a resolution/ar, stroke size , GPU or anything else has anything to do with this problem. it's essential photoshop related bug and is recognized by all artists working closely with clean' lines. other programs like PaintTool SAI, Autodesk SketchBook and etc does not have this issue. switching wacom drivers, windows updates and etc won't solve this.

P.S. the quality of PS strokes has well known issues for centuries now, and haven't been fixed:
http://youtu.be/T1OsByPscuI

ConceptArt.org | Art Sketchbooks, Wacom, and Art Forum (you'll have to read along to get it right)
etc..

this is the reason why most ppl use manga studio or other programs for line / ink work till now. and only do the editing / effects in PS

Report · Oct 15, 2014

I think this erratic behaviour is caused by the lack of any stroke smooth options in Photoshop. I recall that Photoline displayed similar issues, especially when drawing with thin lines on a zoomed out canvas: it would have to interpolate between positions, and would do so quite badly, by introducing jaggies and rough kinks.

After introducing stroke smoothing options, all the issues went away. It is a joy to draw black thin strokes in Photoline now with my Wacom. Even zoomed out in extreme on a large high-res canvas results in beautiful curves.

Mange Studio/Clip Studio, Krita, and even Gimp also offer identical stroke smoothing functionality - and it shows in the quality of especially ink strokes.

You can tell Photoshop has issues by doing this simple test:

- open an A4 document at 800ppi (6614x9354px).

- select a 1px simple brush

- zoom out to 8.3%.

- draw circles and curves at a reasonably fast speed.

When you zoom in, this is what you will see in Photoshop:

Notice the kinks and sharp corners. Also many jaggies. Basically, the strokes are not smooth at all, and look quite abysmal. This is caused by interpolation errors introduced.

Now compare that result with this one:

Nice lines, drawn under identical circumstances in Photoline - EXCEPT for the fact that I actually sped up my strokes 2-3 times compared to the speed I used in Photoshop!!! Just goes to show the difference - and this from an application that does not focus on drawing at all. In Krita and Clip Studio/Manga Studio also no problems with this. As you can tell by glancing at the two examples, stroke smoothing is essential to achieve proper interpolation.

And that is what Photoshop lacks, and it causes issues in line quality. I never do any line work in Photoshop, honestly. Without stroke smoothing control it just is not an option.

Zooming in to 100%+ seems to ease the issue, I would assume it doesn't handle interpolation data when drawing on a zoomed-out canvas (which you would normally do for high-res artwork)!

FIX PLZ!

Hi all

I use Intuos 5 Pro medium tablet. Latest driver 6.3.11-4

Only tempolary fixs when jittering happen is just switch to other program and switch back to PS that's all.

Or If you installed LazyNazumi just pull the panel up and jitter will gone for a while.
I checked evertime jittering occur this method will work perfectly.
And Yes it's no matter are you using LazyNazumi or not this jitter will happen sometime. may be a few second.
or may be long last around 10 minutes
I did test to revert wacom driver to 6.3.6-3 , this driver seem to has a very rare to happen jitter.

Sorry for my bad English anyway but I would like to share my method.

What have you tried? Are you using latest Wacom driver, or have you tried rolling back? A lot of people are saying legacy drivers fix the problem.

Yes right now I'm using latest wacom driver 6.3.11-4

I tried roll back to legacy 6.3.6-3 , but the jittering will not 100 % fixed It will eventually happen again and

yes switching to other program and back to PS will work whatever driver are using.
And since 6.3.6-3 not 100 % fixed ( for me ) but It 's very rare to happen compared to 6.3.11-4
So I try to stay with 6.3.11 from now , I guess the problem is from PS itself not from the hardware driver.

Nice to see some other people are encountering this perplexing issue. It's extremely frustrating, having tried clean driver reinstalls, rolling back to legacy and 6.3.6-3, using LazyNazumi, and the weird behavior of being temporarily fixed when switching to another app. Just a damn shame there's no solutions. Time to use a different program then!

But isn't a Cintiq thing? Least ways, the more you Google, the more frustrated Cintiq users you seem to find. All I can say is thank goodness LNP works with Windows, and I feel bad for Mac users who can't use it. No prizes for guessing which stroked used LNP below.

OK, I just emailed Guillaume, and no surprise, he replied straight back. Not good news for Cintiq jitter or Mac users and LNP I am afraid.

Hi Trevor,

The thread you replied to is about Photoshop's jitter bug, which can happen with or without LNP installed.
From my investigations, that bug is entirely Photoshop's fault, and they refuse to even acknowledge it.

And regarding a Mac version. Believe me, I would love the extra sales... it's just not something I can do right now.

Regards,
Guillaume

It is related to the way Photoshop interpolates between points while drawing. As I have demonstrated before in this thread, zoom out a lot, and draw curvy strokes quickly, either with mouse or pen. Zoom in, and you will find the kinks and jitters.

There are quite a number of Photoshop legacy issues which are completely ignored (it seems) by the developers. This is just one of them. The 16bpc mode issues are another one (banding when zooming out, only 15bpc and information is thrown away). A useless 3d rendering engine.

And JMack can probably list quite a few as well.

For one or more obscure reasons nothing is done to address these - for years and years now. Ah well.

Sometimes Photoshop decides it won't use the high-precision tablet data, and uses Windows screen resolution cursor coordinates instead.

Update 16.06.01 of Lazy Nezumi Pro has an experimental fix for this!

Yes, that is looking pretty bad. Is this a new behaviour? Can you correlate it to a particular event, upgrade, hardware change etc.?

The first question when Windows 8.1 or 10 is involved, is are you using Windows Ink or WinTab. The latter is usually better.

Hi everyone,

This is my first time here so please pardon me if this fix has already been posted! I think this particular fix was simple and overlooked.

Firstly, i am a digital painter working in the game industry and had just upgraded my computer to a high powered workstation laptop for home and installed the latest drivers for a wacom cintiq 22HD (DTK-2200), latest photoshop 2020 and running Windows 10. These 3 probably fight with each other and will continue to do so in the future. My previous sucessful photoshop painting build (at work) was running photoshop 2017 (no longer available though their suscription service) with a windows 7 machine, wacom driver from 2017. It was light and fast, with no jagged lines or lag. It had the PSUserConfig text file hack to bypass windows ink. But back to my new home setup, this was the result of the latest hardware and software.

I uninstalled and reinstalled PS, wacom drivers maybe 30 times trying out different older versions and trying all kinds of combinations of the two. After scouring dozens of webpages and youtube fix videos a few webpages led me to use command prompt and registry editor to muck with computer settings. This turned out to be a nightmare. I gave up, accepted the use of windows ink and those annoying alt, ctrl and shift popups when the key was held and attempted to work. Even with windows ink on, it's still almost impossible, the pressure sensitivity was all off.

I was totally about to give up when i came across a simple youtube fix. Could it possibly be that simple? Under brush settings there is a smoothing option that is now off by default. Check that box and adjust the settings on the top tool bar, i unchecked the default Stroke catch-up and checked Catch -up on Stroke End, with a smoothing setting of 10%. You may want to mess with these settings a bit but...VOILA!! This should give you clean lines!

I hope this helps everyone!

This is not a real solution but just a way to hide the problem as the erratic behavior will continue below the smoothing. Some of us work with no smoothing on, it should still draw silky lines with proper hand movement and it doesn't

This is no solution
