Window height can't increase from the one set at startup (more than half of the screen is white on 1080p→4k)

Issue type

UI bug (incorrect info or interface appearance)

Description with steps to reproduce

1. Start MuseScore, window height will be n
2. Resize window with height larger than n

This is very inconvenient, I have to restart the app multiple times weekly. When Using a 1080p laptop (where the app was started) with 4k presentation display, this is common breakage.

Supporting files, videos and screenshots

(Example image is made by launching app on 1920x1080 display, then rotating it 90° (for 'a4' display).

In which versions of MuseScore Studio is this issue present?

4.6.5

Regression

No. Broken for many major revisions, may be a regression way way back.

Operating system

Arch Linux, Sway

Start by reproducing the window resize behavior on Arch Linux with Sway, launching on a 1080p display and moving or resizing it on a 4K display. Trace the startup height constraint and subsequent resize handling; done means the window can grow beyond its initial height without requiring an application restart.
