--- Comment #1 from Rémi Bernon  ---
The application works for me with virtual desktop disabled.

With virtual desktop disabled it gets stuck in a NtUserEnumDisplayDevices loop,
where it apparently doesn't like us returning display sources with StateFlags
== 0.

This happens with the physical sources which are exposed but without the
`DISPLAY_DEVICE_ATTACHED_TO_DESKTOP` flag. Setting that flat unconditionally
fixes the issue. Then I'm not completely sure we can do that safely.
