--- Comment #4 from Olivier Fourdan <[email protected]> ---
So here is what I think is happening:
1. Press F11 to switch to fullscreen
2. Press F11 to switch back to normal
3. The HW is pretty slow, shell_util_get_content_for_window_actor() takes a
noticeable time to complete
4. the Key release is lost/eaten somehow between gnome-shell and Xwayland
5. Xwayland doesn't get the Key release and therefore performs auto-repeat
6. Xwayland generates Key press/release events sent to the application
7. the application changes its state to/from fullscreen
8. gnome-shell is too busy dealing with the state changes that queue up (as
shell_util_get_content_for_window_actor takes a lot of time) and doesn't
process input events (the pointer is stuck as well)
9. we're doomed, XWayland keeps sending press/release events faster than
gnome-shell can deal wit hteh consequences of the app changing state ...
=> The question is why don't Xwayland get the Key release in the first place,
that's what is causing the key repeat.
(hint, disabling key auto-repeat avoids the issue)
