P: Healing brush & clone stamp tools lagging

I'm currently using the 20.0.5 release. I still experience the lagging of the Spot Healing Brush. It seems as if the tool stops for a second after a few strokes and then continues with it. Very annoying and frustrating!! I have tried out the most relevant solutions that were presented above. Unfortunately, nothing helps.
Working in this way is very counterproductive!!
@Adobe: I hope that a solution will be found very quickly.

I have had all the problems listed above. I have downgraded to 2018 and that did not work. I have tried all the fixes mentioned and they do not work.

HEY ADOBE! This is a serious and widespread problem that has gone unanswered.
For whatever reason the app is slow as molasses on very important processes and does not seem to be limited to Mac users as a number of Windows users have reported the same problems.

I'm on 20.0.4 and on all my machines the healing stamp tool is almost useless. It doesn't just lag it hangs and I need to toggle away from photoshop and back again to make it continue working. This is the most annoying bug I can remember experiencing in a while. It's infuriating. I need to work on fabric all the time and this has slowed me down by maybe 50% FIX IT. 

Thank you, sir. Hiding rulers solved my lag issues.  

Thank you.

I had prob. with lagging clone tool but noticed that if I turned of the rulers everything would be working fine....

I have the same problem. PS is on 20.0.4. When using brush or stamp I can not draw fluently. The tool is drawing dots instead of lines. ADOBE PLEASE FIX THIS. 2019 Version is totally useless for me. I am working on mac pro (black one) power horse.

Everything is very slow. Applying a drop shadow and tweaking it is very laggy. My 2013 iMac does all of that very smooth.

When I am drawing just simple things, the MacBook Pro gets very hot very fast and the fans go crazy.

In the 2015 Version it is a bit better but after a few minutes, the MBP gets hot as well.

What I tried so far:

• reinstalled all Adobe software
• created a new user and testet all of it again
• changed resolutions and disabled true tone
• smc, pram reset
• formatted the hard drive and reinstalled macOS

Here tried to capture the issues:

I am on a
MacBook Pro (15-inch, 2018)2,6 GHz i7
32 GB 24000 MHz DDR4
Radeon Pro 560X

Also Mark, in case you didn't see Rossi's post, he said that hiding the ruler also helped with the brush lag, and the ruler issue was not resolved in 20.0.2.

You're welcome 🙂 This issue should have been addressed with 20.0.2 (Photoshop is currently at 20.0.4), so if you're still seeing the lag on current versions of Photoshop we would want to know.

Thanks!
