Display error after TW `dist-upgrade` to 20231023

[az]

After dist-upgrade from 20231006 to 20231023, certain apps cannot be displayed correctly, e.g. VSCode (see the screenshot below) and Microsoft Edge.

Perhaps the issue is caused by some packages from Packman, because I tried scrollback to 20231006 and “switch system packages” to Packman Essentials Repository, and this display issue occurred. Also the issue is likely affecting Chromium/Electron related apps because Firefox works fine, but VSCode and Edge suffer (haven’t tried Chrome). Does anyone have any clues?

My environment (before dist-upgrade):
Operating System: openSUSE Tumbleweed 20231006
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.10
Kernel Version: 6.5.4-1-default (64-bit)
Graphics Platform: X11

See this Reply for the most likely fix:

Chromium and chromium based browsers (Vivaldi) not displaying content correctly

I had a similar issue recently with Chrome, Chrome Beta, Brave … no doubt Chromium will have it too. This fix works for me. For each affected app, I had to delete the associated GPUCache sub-directory. There is quite a few to delete, search for them like this find ~/ -type d -name GPUCache (in the users home directory) They can all be deleted in one fell swoop with: find ~/ -type d -name GPUCache -exec rm -rf {} + … but do it at your own risk. I actually renamed them to “GPUCache–ho…

Verified to be working. Life saver!
