P: Healing brush & clone stamp tools lagging

[FeedbackCommunityMember]

I just recently updated to Adobe Photoshop CC 2019, and my healing brush tools and clone stamp tool lags when I use it.  I had no prior issues with CC 2018.  What gives?

HI Anthony,

Try go to Preferences > Technology Previews and unchecking "Enable Preserve Details 2.0 Upscale", then quit and restart PS. Does that help with performance?

Thanks,
Adam

Same problem here. Clone stamp performance is horrible and it seems that they changed the algorithm behind it. Doesn't work that flawless anymore. 😞

Adam@mmg, your solution doesn't work either.

Same problem.  When zoomed in at 100% the lag is really bad.  Smoothing is switched off and tried the suggestion Adam proposed but to no avail.

Hi Everyone,

A user on this thread said: "What worked for me is turning off, 'Enable Preserve Details 2.0 Upscale" under the Technology Preview preference.'" Would you please try that and let me know if this works for you?

Thanks,
Hannah

It didn't work for me.

PS 2019 – I'm experiencing brush lag, as well. Opened PS 2018 to test and no brush lag.

I tried turning off 'Enable Preserve Details 2.0 Upscale' and restarting without improvement. Things to note:

• Resolution doesn't matter. Same brush lag with a 500 x 500 px @ 72dpi  and 2,000 x 2,000 px @ 300 dpi files.
• Mouse and Wacom show same brush stroke delay. It looks like a .5 to 1 second delay
• Using default PS Brush – Soft Round Opacity Pressure
• Delay with smoothing On or Off

I've noticed that lag is on the initial stroke. If you don't pick up your brush, then lag disappears and the brush is very responsive. Unfortunately, I do a lot of brush stroke, sample new color, brush stroke, sample a new color, etc. This means I'm picking up my brush constantly as I blend, which leads to excruciating lag. 

Same using a mouse. Click and drag, the initial stroke is lagging. If I keep the mouse button depressed while I stroke, then it's responsive.

Hope this helps drill down to the problem behind the lag issue.

Hi Rossi,

Thanks for trying that workaround. Would you please go to Help > System Info and then copy and paste the contents of that folder either here in a reply or email them to me? I'll paste my email below.

Thanks,

Hi guys! I can confirm same issue on both of my mac's. Spinning and laggy curser when using the healing brush & clone tool. Happened right after updating to the new version of PS CC 2019. Have been chatting with Adobe support on twitter for two days now and have tried everything (alsmost) 🙂 without any luck. Let me know if I can help supplying any useful information. 

Best,
Søren

Hi! I’m having the same problems on an iMac (Retina 4k, 2017 i5, 16gb, Radeon Pro 555 2gb, OS 10.13.6) Everything worked smooth with cc2018, after the update to cc2019 the healing brush, clone stamp and zooming lags. I’ve tried the ‘enable preserve details’ fix but that does not work. I really hope you can find the solution, editing is very frustrating right now.

I have added a video that shows the lag with just zooming on an image. it takes a few seconds to work, after that it is fine until you switch to another tool, then the lagging returns. Especially with the healing brush it is very difficult to work like this.

I have the same problem on my iMac but it seems that it is isolated to my wacom intuos pro. When I zoom with my mouse the zoom reacts right away but with the wacom I need to keep the pen down for that half second before it starts zooming. I have tried different settings for my pen pressure in wacom settings but that doesn't change anything. Really annoying with this lag...!

I have the lag also. AND....the Healing brush seems to do things differently....not as clean as 2018

[FeedbackCommunityMember]

Try to hide the ruler. It should help a bit.

[FeedbackCommunityMember]

A bit? When i hide the ruler there's no lag at all.. perfect! Thanks!

[Kirk Voclain]

I have to say I find EXACTLY the same thing.....hiding the ruler is solving this problem in a very large way!!! THANKS!!!

[FeedbackCommunityMember]

Thanks, you just saved our workflow! Who would have thought?

[Jose Paredes]

It does not solve it completely but it helps a lot... Thank you.

[artkeh]

Yeah, strange but true. The lag is terrible but almost goes away completely once the rulers are hidden.

[KODECPhotography]

It makes no difference on my system.

[FeedbackCommunityMember]

Yep, made a huge difference here. I have just tried it very quickly but noticed an improvement! Thanks for the tip!

[Stephen Newport]

Same problem here, spinning progress wheel as I brush, sometimes strokes/drags don't activate. Most noticeable in healing brush, but does the same thing with the move and stamp tool.

1. Update to Mojave
2. Updated Photoshop
3. Started painting with the brush tool on a simple file with layers
4. The cursor icon switches to the Spinning Wait Cursor while painting for about
5 seconds
6. Happens with both my wacom pen and mouse
7. The brush tool is not lagging when this wait cursor appears.It's annoying and I don't recall this happing ever before the OSX update.All drivers and software is up to date.

[Jose Paredes]

Exactly the same happend to me. Hidding the ruler helped to me.

i'm having a similar problem to Andy and Jose, although in my case it's triggered only under specific conditions and doesn't seem to be altered by the ruler trick (other than the overall performance decrease that enabling rulers now instantly inflicts across all program functions)

when using my wacom intuous, the paint tool throws a busy cursor when rapid strokes are combined with rapid pressure variance. i made a video illustrating the problem. sorry for my grumpy tone in it, just a very frustrating problem.

additionally, drawing with the pen seems to cause quicktime's screen recording to glitch out, as seen in the video. no idea what's going on there —it didn't look jumpy when i was actually painting / recording the video. could be related, perhaps mohave changed something with the cursor handling because the "show mouse clicks while recording" function isn't behaving correctly in photoshop either (the circle only appears when the busy cursor is trigged, in fact). note that screen recording works perfectly with all other programs i've tried, only photoshop produces this weirdness and only when using my wacom pen.

"paint tool" above should be "brush tool" obviously, my bad
