Leaving a trail behind means that gnome-shell doesn't know it's meant to be painting any wallpaper. So that does sound related to monitor issues.
Just to make sure it's not caused by another bug we have in progress, please try: gnome-extensions disable d...@rastersoft.com and log in again. Please also try *without* the HDMI monitor connected. It looks like it's configured to mirror the laptop display... is that because the laptop lid is closed? -- 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/2097003 Title: gnome-shell crashed with SIGABRT [libmutter:ERROR:../src/core/window.c:5937:meta_window_get_work_area_for_logical_monitor: assertion failed: (logical_monitor)] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2097003/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
