It would really help us diagnose the problem if someone could send me one of the corrupted files.  If you'd be willing to do so, please contact me directly at first name dot last name at adobe dot com. Thanks, Adam ... View more

If you suspect a VRAM leak, can you disable the GPU (uncheck Use Graphics Processor in PS performance preferences) and see if you can still reproduce.  We thought we had this issue addressed, but apparently not? ... View more

If you're still seeing this issue, try disabling the Halide Bottlenecks plug-in.  You can do so by doing the following: 1.  Cntrl or right-click on the Adobe Photoshop CC 2018 application package and choose Show Package Contents 2.  navigate to Contents\Required\Plug-Ins\Extensions\ 3.  rename the HalideBottlenecks.plugin by adding a '~' at the beginning of the plugin name (it should be ~HalideBottlenecks.plugin when you're done) 4.  Quit and re-launch PS Please let me know if you're still seeing the corruption after this change. Thanks, Adam PS - if the issue is also occurring on Windows, go to the app folder and navigate to Required\Plug-Ins\Extensions then follow steps 3 & 4 above. ... View more

Out of curiosity, how much space do you have available on your primary/OS drive (not your scratch volumes)? ... View more

Is it all fields in the performance preferences or just the RAM% field that you can't edit? Also, the amount of ram free and in use can be reported wrong by system info, so it would be helpful to check Task Manager and see what the OS reports PS to be using.  My guess is more than 8MB, but I may be wrong. ...

We're aware of the issue (Mac only btw), and are working to get a fix out to customers asap.  Thanks. ... View more

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? ... View more

Adobe folk here - we can confirm brush smoothing being enabled triggers the slowdown.  Disabling it should get the healing brush working again as it did in PS CC 2017.  In the meantime we'll continue to debug the issue here and try to get a fix out asap.  Thanks again for everyone's help with this. ...

Looks like my suggestion came a few minutes late 🙂 I'm glad we have a workaround for now, we'll see about getting a proper fix out asap.  Thanks again for everyone's help getting to the bottom of this. ... View more

Try turning off paint smoothing from the tool options bar when the brush tool is active (the default is 10%, change that value to 0%).  And then use the healing brush again. Is it still slow? ... View more

I will post here when a solution becomes available.  In the meantime you can download an older version of the nVidia driver to workaround this issue. ... View more

There's a known issue with the latest nVidia drivers which could cause Focus Area to fail.  Either use the integrated Intel GPU, or roll back to an older driver.  We're planning on addressing this issue with an update asap.  Thanks. ... View more

Matthew, Could you do us a favor and use Activity Monitor to sample Photoshop while it takes 20 secs for healing to complete?  (on your larger image) To do that, launch Activity Monitor, select the Photoshop process, start your heal in PS, then go back to Activity Monitor and click option-cmd-S.  Then please post the sample here.  It may give us a clue as to why it is taking so long to complete. Thanks. ... View more

Also it would be helpful to know if you are driving PS with a mouse or tablet.  Thanks. ... View more

Can the people affected by this please help us by providing what type of file they're seeing this on?  8bit, 16bit? RGB, large, small, amount of layers?  Any info would be helpful for us in trying to reproduce this.  Thanks. ... View more

We've had other reports of slow brush performance fixed with a preference reset and restart. If you haven't tried this yet, please do: use the button "Reset Preferences on Quit" from Preferences > General, then restart your system.  Does the lag still occur?  Please let me know.  Thanks. ...

Steve, Can you take a look at your console log to see if the OS or Photoshop is reporting anything there?  Also, it would be worth looking at activity monitor to see if PS CC 2018 is using more CPU when using those tools compared to previous versions.  Thanks. ... View more

Hi Matt, Thanks for the updated information.  I'd like to get the action you're running on the files to try to reproduce the issue you're seeing here.  Can you email me directly at:  first name dot last name at adobe dot com Thanks, Adam ... View more

Hi Matt, Can you try an experiment for me?  Try disabling the GPU for Photoshop by going to Preferences > Performance and uncheck "Use Graphics Processor", then quit and restart Photoshop.  To help troubleshoot this, I need to know if the issue still occurs even if the GPU is disabled (you can always re-enable it after running the overnight test for me). Thanks, Adam ... View more

Hi Matt, The problem we fixed is likely unrelated to the issue you describe above.  Can you tell me how many files are being processed? Thanks, Adam ... View more

Hi Emmanuel, We have a fix in-hand for this.  Let me know if you're interested in testing it out. Thanks,Adam ... View more

Hi, can you confirm that you're using the latest release of Photoshop CC 2017 (go to Photoshop Help > System Info and the first line should have the exact build number - you can post that here).  The text performance issues should be resolved in that build.  If not, please let me know.  Thanks. ...
