Description Cameron Gutman 2021-01-28 01:48:20 UTC 
GNOME Mutter on X11 requires keyboard grab for certain important functionality like window resizing, interaction with the application context menu, and opening the Activites view. To allow Mutter to grab the keyboard as needed, we'll ungrab when the mouse leaves our window.

This problem has been there since initial support for keyboard grab in X11, but it wasn't reachable previously because mouse grab prevented those controls from actually being accessible (since the mouse couldn't move outside the window to reach them).

Some investigation done by the VirtualBox is here: https://www.virtualbox.org/ticket/10842#comment:3

The approach I'm taking here matches what VirtualBox ultimately decided to do: https://github.com/mdaniel/virtualbox-org-svn-vbox-trunk/blob/7661adb1ab02277f10f861bfbe03a81b78612aad/src/VBox/RDP/client-1.8.4/xwin.c#L2525
