Maximized window bugged with some Windows scaling values
S3 - Major
1) Setup your Windows "Scaling" option to be 125% or 175%
2) Open MuseScore4
3) Maximize it
As you can see, the top of the window has a weird white line, and the left/right/bottom are not attached to the borders of the screen, as a maximized window should be.
