I have this problem on two machines, both using the 340 Nvidia driver and running Ubuntu 19.10.
On one machine, with a Geforce 330M, only the lockscreen gets corrupted. On the other, running Geforce 8600M, both the lockscreen and wallpaper get corrupted. This didn't used to happen on 18.04, I was hoping to get better performance that came with 19.10 and now there's this. :-( With Nvidia EOLing the 340 driver recently, I was hoping to get another 5 years of both machines with Ubuntu 20.04 (if the driver continues working there at all), so hoping this does get fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
