Rémi Bernon (@rbernon) commented about dlls/winex11.drv/desktop.c:
xev.xclient.display = display; xev.xclient.send_event = True; xev.xclient.format = 32; if (width == host_primary_rect.right - host_primary_rect.left && height == host_primary_rect.bottom - host_primary_rect.top)
This could probably use `is_desktop_fullscreen` instead.
