Screencast of the blank extra window for MLO

After I launch `wine mlo.exe`, KDE Plasma shows two windows for MLO, one of
them being blank. When I try to switch to it, apparently nothing happens. There
is (correctly) only one task bar/panel button.

KDE Neon 5.21.5 on Ubuntu 20.4.1, current MLO (5.1.1). HiDPI scaling set to
144.

This looks like a regression because I've never seen this double window
behavior before, but I haven't run MLO on KDE/Plasma before (only GNOME).

```sh
$ wine mlo.exe
