The bug re-occurred, after manually building libwayland with debugging symbols.
So I could do more debugging, and I think this Ubuntu bug needs to be reassigned to Xwayland. I have filed more details in the upstream Xwayland tracker. https://gitlab.freedesktop.org/xorg/xserver/-/issues/1648 ** Bug watch added: gitlab.freedesktop.org/xorg/xserver/-/issues #1648 https://gitlab.freedesktop.org/xorg/xserver/-/issues/1648 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2043517 Title: gnome-shell on non-active VT busy-loops through libwayland-server.so (sometimes) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2043517/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
