Just updated to Photoshop 2020 - gray screen redraw.

Exactly the same issue here

I posted a video of whats going on. This issue is really really really annoying and have no idea how to stop this from happening. Sometimes it even gets stuck like what's happening in the video(however I think doing a quicktime screen recording sometimes slows down my computer, which is why I think it nevers shows). It usually shows after I hide/show a layer. 

Had this issue occur to a user on a Mid-2017 MacBook Pro running Mojave 10.14.6. Ran through all the suggested workarounds in the post but nothing solved the issue. Uninstalled Creative Cloud and all other apps using the guides here but:

• https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html

The issue persisted after installing the latest version of Photoshop 21.2. Ended up uninstalling Photoshop 21.2 and reinstalled using an older version 20.0.9 which seems to have solved the issue so far. Has anyone been able to revert back to an older version like 21.1.3 or 21.1.2 to see if the issue is resolved there?

Having the same issue and nothing is fixing it! Really putting a clog in my workstream, regretting updating entirely

I am having the same issue. Updated to Photoshop 21.2 and this issue is so bad that the program is almost unusable. Please provide a fix Adobe, my iMac is brand new.

I Fixed it.

Preferences > Performance > Check the Use Graphics Processor
Select Advance Setting and SELECT first 3 options, and leave 30 bit NOT SELECTED.

Restart your Photoshop and it worked for me. No more gray artboards or display problems with texts.

Hope it helps.

Same issue since the recent 2020 update. Reverted back to the older version of PS until this is resovled. It is impossible to work when every time you click a text field everything turns gray for a moment and then a moment later only part of the workspace returns. Tried all of the solutions posted here and nothing is working. This started with the newest update with files that have multiple artboards... but to be fair PS has always sucked at handling artboards.

PS becoming less reliable with every update. Sometimes if you open a file, then close it, and open another file, the entier workspace is just gray, only showing the menus and tools. Great stuff.

I got exactly the same problem here. as soon as I click outside the app. the image turns gray. I have to zoom in or out to get it back. I thought it was an e-gpu issue but it seem I am not the only one experiencing this.

Same issue here since updating to 2020 a couple of days ago. Gray screen redraw frequently. Happens 100% of the time if I switch to another app and switch back to Photoshop, and happens frequently while using the app as well. I have to force a screen redraw by zooming/etc. in order to get back to work in my document. Very frustrating and should have been caught in development.

I'm running Mac OS Catalina on a Mac Pro 7,1 tower with a Radeon Pro 580X graphics card connected to a Dell 4K display.

I've tried disabling "Use Graphics Processor" and restarting, same effect. 

Same problem !.... 😞
