gnome-shell crashes when pressing Ctrl+Super in a GTK application
Steps to reproduce:
- Start a GNOME Wayland session
- Open a GTK application (tested with GNOME Terminal, Tilix, Dino, Thunderbird)
- Click on any text input field in the application to focus it
- Press Ctrl+Super simultaneously
What happens:
gnome-shell crashes
Tested with current mutter and gnome-shell releases (3.34.0) in Fedora 31 as well as their current master branches. Can't reproduce with Qt applications (neither native Wayland nor XWayland ones). Doesn't always trigger, try clicking into the text field and pressing the key combination a few times.
