--- Comment #5 from Rémi Bernon  ---
The virtual desktop mode should be fixed after
b3c1bd33e0c913def8f214baf7875f2ef8a46e6e, but there's still some failures when
neither virtual desktop mode nor fullscreen window clipping options are used.

In this case clip_fullscreen_window still tries to clip the cursor to the
entire virtual screen. I'm not completely sure to understand why it was doing
that, because I don't think the cursor can go beyond the virtual screen anyway,
and I'm tempted to simply not clip fullscreen windows if the option is
disabled.
