P: Healing and Spot Healing Brush Lag

[Stephen Newport]

In most recent 2018 update, healing and spot healing brush have become much less responsive, sometimes taking multiple seconds after completion of stroke to affect the image.

I've done the regular things like turning off OpenCL and changing other performance options... no change.

I'm having the same issue also. Tried everything, several PS performance settings, maintenance routines on my Mac, deleting caches....all of it after a few minutes working, the healing brush starts lagging again. Will this be fixed with a patch or should I go back to previous version.

[Stephen Newport]

Did you turn smoothing down to 0%? I didn't turn "off" smoothing, I just dragged the slider to zero in the tool bar and everything is working properly now

The line is easy to remove. Go Preferences > Cursors > then uncheck Show Brush Leash Wile Smoothing.

FYI I had to call about this too as it was making me bananas, I couldn't clearly see the skin I was dodging with that trailing hot pink line.

I've been working with this stupid lag issue all weekend as I have major retouching deadlines,

I've learned that resetting tool preferences as suggested by the Adobe Tech Support is a waste of time. You just have to RESTART Photoshop. Don't lose your settings anymore just restart.

The best thing to do is use the healing brush first on anything and everything you need it for. Once you switch through a few other tools it will develop the lag. The only way to fix this is to save your work and restart photoshop. 

I think we should all go Tweet about it, it's the fastest way to get a response from Adobe, I know from past experience...

Tweet your brush lag complaints @AdobeCare and they will respond - quickly.

Have you tried the smoothing solve above?

[Earth Oliver]

if you're on deadline and the lag is interfering that much, why not use CC2017 until they fix??

[Adam Jerugim]

For those still seeing the issue, please go to the Brush Settings panel and disable Brush Smoothing (uncheck the box).  Then quit and restart PS.  Does the problem still occur after re-launching?

[poshqueen]

Good point, I just didn't. I just needed to keep going and a few restarts here and there were manageable for the time, but not forever. Hopefully Adobe corrects this quickly.

If you note the other thread about brush smoothing, a poster uncovered that brush Smoothing doesn't hold through a relaunch. So that cannot work. The second you use another tool, the lag will start to return because in the Brush Settings panel, Smoothing is once again enabled. It ignores the LOCK icon.

I've only had success when turning off Smoothing and sticking to that session. Then it stays off.

[Stephen Newport]

I don't have to uncheck smoothing, I just have to turn it down to zero (in the top panel), and it stays that way between relaunches.

Hey guys,

Discovered another brush performance hit in the new 2018 that you may want to test out if you're having these issues, brush "resizing " is much more laggy and smoothing settings do not affect this. I've created a new post for this at the link below, it would be helpful to get some me-too's on it:

Yeah, that thread got buried quickly.
PS 2018: Smoothing keeps getting re-enabled despite being disabled and locked in Brush & Tool Preset...

By the way, fresh install of CC on a fresh install of the OS.

Isn't that a bit too much trouble to ask?

Terrible bug for the 19th Photoshop release. You should do some proper beta testing before you release a new major version Adobe... Anyways, disable smoothing completely with the checkmark from the 'Brush Settings' panel works for me, although sometimes it enables itself again after restart. Using the patch tool is the best alternative for me as I use the stamp tool with a low opacity for other purposes.

If you do very intensive retouching, like me, just revert your Photoshop to v18. Install it from the CC app. There are not to many new useful features anyway  besides the smoothing, which is buggy.

[Stephen Newport]

Bragi,
We found a temporary solution and they are working on patching it.... I'm not sure how they didn't catch this one, but bugs happen. You don't have to use the solution if you don't want.

[Stephen Newport]

This isn't the solution guys, its posted further down. Slide the smoothing slider down to 0%

[Bkort]

That is good news 🙂

Window > Brush Settings and then uncheck the box below.

Also be advised that there is a known issue with smoothing reselecting every time you open a new session. We are looking into this but in the meanwhile it's something to be aware of.

Bottom line: Smoothing has to be turned off with each launch.

I've been seeing this also.  PS 2018 is full of bugs and is unusable.  In addition to this problem, I've been seeing severe issues with rendering Masks depending on the level of zoom.  The ALT key is broken and this means any and all shortcuts that rely on it are useless.  I couldn't revert back to PS 2017 fast enough.  

[Hannah Nicollet]

At present, smoothing must be disabled at the start of each new Photoshop session. We are aware of the problem and our engineers are looking into it.

[Earth Oliver]

Are you using the legacy healing tool or the one which has Diffusion options?

[Earth Oliver]

I think the issue with Smoothing not carrying over is working as intended? Brush presets generally revert back to their saved state when you make a change and then restart the app. To make the smooth option stick, you'd need to create a new brush with that option toggled off.

[poshqueen]

This did not work for me

[FeedbackCommunityMember]

Nope. In fact, I've turned OFF Shape Dynamics, locking it, for the default round brushes before and had them stay off, so if they don't revert, no reason Smoothing should. But it does—this after a restart:

The spot healing brush is VERY slow in PS CC2018.
The patch tool is also sluggish.

These are both instant on CC2017
