Application window wrapps the MuseCore application window in Maximized mode

1) Use two 4K Monitors (3840x2160 px) with scaling of 175% (extended View)
2) Start MuseScore 4
OS: Windows 10 Version 2009, Arch.: x86_64, MuseScore version (64-bit): 4.0.0-223472200, revision: 5485621
3) Maximize Window
4) White program window arround MuseScore is visible, I can notice the red X (close icon of the window) on the upper right area of the display
I can guess the window mode (of the host window) is not configured correctly because the wrapping window is visible which does not seam to be intended.
The #337940: Menu Bar does not display correctly when window is maximized (Multi-monitor setup) seams to be the same issue.
