I believe, libmutter package (libmutter-10-0 to be exact) should be upgraded to fix the problem, as mutter binary by itself isn't used by gnome-shell.
I couldn't upgrade libmutter-10-0 selectively as per https://wiki.ubuntu.com/Testing/EnableProposed due to some errors. I'm not experienced enough in Ubuntu package management system to resolve them. I can confirm though, that a 'full' upgrade from -proposed does fix the issue for me. -- 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/1971693 Title: Alt+Tab is broken for Java (AWT/Swing) apps in Wayland session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1971693/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
