P: Switching between documents in Full Screen Mode displays black areas (macOS GPU issue)

[sam_s]

I use switching between images using Command ~ shortcut in the Full Screen Mode with Menu Bar, or Full Screen Mode to compare the changes I've done between 2 versions of an image.

This isn't working on 21.1.0 on the new Mac Pro. When in Full Screen Mode (with or without Menu Bar), once I switch between 2 images twice, regardless if I select them in the menu or press Command ~ the image shifts to the left half of the screen and the rest of the screen is black.

Screengrab attached, the pixellated thing is sample image. It's not showing anything in the black area.




The only way to get rid of this problem is to untick 'Use Graphics Processor' in Performance, which obviously I don't want to do. The settings in 'Advanced Graphics Processor Settings' have no effect on it, tried unticking all boxes and using 'Basic' drawing mode, and some other combinations.

System info:
Mac Pro 7,1 2019
GPU AMD 580X
OS X Catalina 10.15.3

I tried 21.1.0 on my old 2013 Mac Pro and no problems. Though it runs on Mojave, not Catalina.

Update:
"Downgrading" to 21.0.3 has removed the problem, so this isn't something intrinsic to the 580X graphics card on new Mac Pro.

If there isn't some other annoying bug I'll stay on this version until it's fixed, it's really important for my workflow to be able to flick between images using Command ~ in Full Screen mode.

I've had to downgrade to 21.0.3 for different problems, but just so you know, ctrl+tab functions the same as command+~ (as long as you don't have a curves dialog open, then it moves between points)

Indeed, thanks for tip!

Hi Sam,

Your post is very informative and thorough. Thanks so much for your help! This is under investigation but I added your info to the case.

Thanks very much for looking at this Hannah.

Just an update - this was still an issue in 21.1.2, so have rolled back. But tried to explore more about it before doing that.

The issue happens whenever tabs aren't used. Please see video.

It starts with 21.1.2 with freshly reset preferences, and all is fine with Command ~ in Full Screen Mode and Full Screen with Menus.

Then at about 0:28 I free the documents from their tabs, and the issue appears again.

This issue should be fixed in the 21.2 update that went out this AM. Let us know if you're still having trouble.

Thanks very much for looking into this guys.

I've updated and tested 21.2 with freshly reset prefs and unfortunately still having trouble. It's still like in the video above.

It only happens when the documents are in windows, not in tabs.

For a while I've been using the latest version regardless. The workaround for this is Window - Arrange - Consolidate All to Tabs. I like the windows though, as I can drag layers between documents easily, so after I'm done with visually comparing the documents in full screen mode I would run Window - Arrange - Float All in Windows.

Anyways, thanks for having this on your radar.  I'd be happy to beta test for this problem if you'd like me to.

Looking forward to explore the new features / other fixes in this version.

I would like to add, if I have multiple documents. Lets say 5. If I switch trough docs screen cuts black mostly after doc5 switches to the doc1 and then glitch stays unless you go out of full screen mode.

Is Photoshop spanning multiple displays?

Hey!

Its like this:

Sometimes it does not help to quit the program, but I have to restart the computer.

Have had the same problem with my Imac and now my brand new Macbok Pro 16 ".
Has the latest software on Macbok.
