Gnome Shell crashes when Firefox gets dragged over a wayland app
OS: Arch Linux (updated today)
gnome-shell version: 3.34.4
This issue appears under Wayland
I've found that I can reliably crash gnome-shell. It happens when I drag a firefox tab over another window.
If I run
export MOZ_ENABLE_WAYLAND=1 and launch firefox then I can't cause the crash. It only happens when firefox is using Xwayland.
Steps to reproduce
- Open a window running under wayland (such as gnome-terminal, gnome-settings, or nautilus)
- Open firefox not running wayland natively
- Place the windows on the screen so that they don't overlap
- Grab firefox on the tab bar where the window title gets displayed. Drag it over the non-firefox application.
The UI locks up, then I end up at a TTY - no more GUI.
What did you expect to happen
I expected firefox to move on the screen without crashing the shell.
Relevant logs, screenshots, screencasts etc.
I've attached a coredump. gnome-crash-coredump.txt
