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?

I'm also now having this problem... PLUS when I try to click a clone a single spot and then move my mouse to the next spot and click, it clones an entire line between the first and second. I'm not holding the shift key down which does that as expected. It's as if Photoslop isn't recognizing that there's no keys pressed. HELP!

I'm hiding rulers, disabled technology previews, touchbar, normal drawing mode, enabled legacy compositing...even ran this terminal 

defaults write -g PhotoshopForceLegacyPaintMode -bool Yes

I'm also having a problem. When I use clone stamp, healing brush or brush tool, I can't see the tool. When I press  mouse key to use any of this tool, the circle dissapears. It is very hard to work like that. What would solve this problem? Anyone knows?

@simon, regarding the visibility of the tool, try hitting the caps lock key

This reply was created from a merged topic originally titled Photoshop cc 2019 makes my MacBook Pro 15" 2018 run very hot in simple tasks and ....

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 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.

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.

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 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.

Clone stamp tool in the latest release (20.0.5) is simply NOT USABLE. Lags, selecting an area takes 2 seconds, it often does not register at all, it copies from a different spot than selected. It is useless in its current state. 

Rolled back to 19.1.8 - works like a charm. Windows 10.
