@jagosta: does it only crash if the dialogs are on different monitors? That's what I find.
FWIW, I tried the live USB, but ootb Ubuntu 19.10 doesn't recognise the HDMI monitor, so I can't do dual displays, and I also tried a VirtualBox guest, but even after installing Ubuntu 19.10 and guest drivers, Ubuntu 19.10 doesn't correctly recognise the second monitor, so I can't do dual displays. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849249 Title: gnome-shell crashed with SIGABRT: mutter:ERROR:../src/core/window.c:4841:set_workspace_state: assertion failed: (workspace == NULL) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1849249/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
