I'm on Ubuntu 20.04, using the nvidia-driver-440, and I am also experiencing wallpaper corruption issues whenever I unlock my desktop.
My current workaround is to do sudo apt install --reinstall ubuntu-wallpapers This restores the picture, but eventually it gets corrupted again. I previously also saw some corruption in the top bar and in the dock icons, but this seems to have cleared up. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1855757 Title: [nvidia] Background image corrupted after standby To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1855757/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
