Reproducible crash with master branch
I can reproduce the crash every time with transmission torrent client, with the following:
- On the main window, right-click on any torrent and select "Set Location..."
- On the opening pop-up window, choose whatever settings you wish, and click "Apply"
- A new popup window opens, and after a few seconds, the shell crashes with the following error in journal:
mutter:ERROR:../mutter/src/core/window.c:1521:meta_window_unmanage: assertion failed: (window->display->focus_window != window)
I've only tested this under wayland, and transmission is a native wayland window (not Xwayland). I've not observed the crash with other applications so far.
Update: The crash does not seem to happen under Xorg according to my further testing.
