Thanks, now we just need to figure out who owns window 0x2000003. Assuming you haven't logged out yet, please run:
xrestop -b > xrestop.txt and attach the resulting text file here. You should also be able to find out which process owns the black window with: xprop -id 0x2000003 | grep _NET_WM_PID -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970141 Title: [focal] Desktop is mostly covered by a black rectangle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1970141/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
