I updated my Macbook Pro to Big Sur and now I have problems with my photoshop like Liquify isn't working properly with the screen popping up completely black. Not even just the liquify image screen but the buttons too are completely blacked out. I can guess at what I'm clicking on and the liquify works, I just can't see what I'm doing when I'm doing it. Same with other tools too. I tried unclicking the Use Graphics Processor in Preferences with no avail. I also tried resetting my preferences and it didn’t work. When i quit photoshop and restart it i get this "Due to a problem initializing CC Libraries, existing links to library graphics will appear broken and new link creation may fail."
Photoshop has known problems with Liquify and other filters on Macs running Big Sur. That restart message is another known problem. See the workaounds on this page: https://helpx.adobe.com/photoshop/kb/photoshop-and-macos-big-sur.html#big-sur-known-issues
Unfortunately, the fix described is like Greek to me. Hopefully someone with more tech knowledge than I will soon answer your post. If it were me, I would also try putting the gist of that language in a post title with "Meaning?"
If you do a search in the Community for "Big Sur," you may find previous posts regarding the same problems and, hopefully some helpful advice.
I have the exact same problem. MacAir M1 running on Big Sur, Photoshop CC 2019. The dialog appears completely normal on external monitor, though
Were you able to solve this? I've been having the same issue for some time now as well
Yes, I either use an external monitor or open photoshop in low resolution mode if I have to work directly on my mac screen.
Get Info > check on Open in Low Resolution box before you launch Photoshop.
