A Problem on the latest Photoshop 21.2: Blank Gray Canvas

[designer@indigointer.com]

The symptom is when you go to other app and come back to Photoshop, the canvas becomes blank gray. I have to move some objects or hide/unhide some layers for the screen to come back again.  See the attached you to see what it's like.

This is so annoying because we have to use back and forth between apps. 

I've tried changed GPU preference (Basic/Advanced and even NO GPU) and re-started photoshop but it didn't solve at all. So I think it's not about the GPU setting.

Finally, I find a solution but it's not actually practical but it worked. I noticed that it happened to some artworks that has Artboards so i tried to clear all artboards inside that artwork. The symptom is gone (not entirely but it happens less)

To Adobe, please fix ASAP. We need to use Artboards. 
To fellow users, if you have better solutions, please share.

Thanks.

Hi, It seems a GPU related issue...  Have you updated the OS and the graphic card driver?

[designer@indigointer.com]

I thought it too, so I've updated the system and all patches to the latest but it didn't work.

My current system is macOS Catalina 10.15.5.

Moreover, I've also tried disabled the GPU but it still did not work.

Hi

Check to see if legacy compositing is enabled in preferences, if it is disable it and restart Photoshop, this has fixed other GPU related issues with version 21.2, worth a try

I've tried this too. It didnt' work.

You can report it as a bug on the Adobe Feedback Forum

I've re-posted this post there as you suggested already. Thanks so much.

The symptom also occurs for the artworks having Layer Group too. 

It's too annoying so I've downgraded to version 21.13 to solve this problem.

Same problem here and absolutely nothing helps. It's so ANNOYING.

Seems like I have to downgrade the version.

The bug kicks in when I try to edit text. As you can see in the vid above, the artboard label disappears, and the transform controls become dotted. This bug is an absolute nightmare when working with artboards, please fix it Adobe!

Hi, did you ever find a solution to this problem? I am currently having the same issue and I'm losing my patience very quickly!
