This is proposing changing QEMU behaviour to workaround a problem whose behaviour varies based on what 3rd party software QEMU is running on What you say "window managers" are you referring to a traditional X11 based host display only, or does the problem also exist on modern Wayland host display ? If the problem is confined to X11, that would steer towards saying we shouldn't try to workaround it given that X11 is very much obsolete at this point.
