gnome shell freezes when qt (wayland) applications are dragged between screens
Seen this on multiple machines and multiple versions of gnome-shell/mutter.
This time it was:
- mutter 3.34.1
- gnome-shell 3.34.1
- Qt 5.14.0 RC1 (also with older versions)
export QT_QPA_PLATFORM=wayland(to circumvent blacklisting of wayland on gnome-shell)
- Run a Qt application, such as
- drag the window from one monitor to another.
Mutter freezes, cannot change to a tty.
