Application Windows Flickering, black surrounding windows, or blank (black) app window
Last modified: 2023-11-27 15:55:55 UTC
The latest update to 6.6.2 (?) completely breaks my application windows. Brave browser won't render any images, just displays some colors, or has window echoing. My VPN app doesn't generate at all, just a black window. I'm using KDE. Gnome was way worse. Rolled back to 6.6.1-1, and don't have any issues. Attempted a reinstall of the update, and got same problem. 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09) 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

This post help solved my issue (below). Had something to do with the gpu cache, and removing the folders for browser and vpn app fixed it. Here's the instructions I followed, but again a bit more detailed is linked. > 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. https://forums.opensuse.org/t/chromium-and-chromium-based-browsers-vivaldi-not-displaying-content-correctly/167660/2
FWIW, a similar report in bug 1217484
