Shift+Windows+LeftArrow doesn't shift screens; results in white screen

I have more than one screen. To shift a window from one screen to the other, I use Shift+Windows+LeftArrow and Shift+Windows+RightArrow. When I do this inside MuseScore4, MuseScore4 does move to the other screen, but it's a totally white screen. I use the task bar to X out of it.

This seems to be a genuine bug. I've never had a problem using this method to shift screens with any other software.

For a reference, I think this procedure is listed somewhere on this page: https://support.microsoft.com/en-us/windows/keyboard-shortcuts-in-windo…

It's not a big problem for me. But I just thought I'd tell you.

Thanks for the software!!!
