UI Goes Strangely Bright with Inverted Score in Dark Mode

Issue type

UI bug (incorrect info or interface appearance)

Description with steps to reproduce

Upon opening the app & selecting a score (previously having set the app to dark mode, as well as having the invert score option ticked), the whole app gets much brighter than expected—a pale purplish/reddish hue. This makes everything harder to read (including the settings) & could be considered to look bad. This issue also affects light mode, although I don't use it enough to know anything specific.

The only workaround is to open a new instance of MuseScore & closing that score. This somehow reverts the 1st instance to normal. Repeat for subsequent open windows.

Normal hex values for Main UI: #2D2D30 Score Background: #000000

Observed hex values for Main UI: #807F89 Score Background: #1D191A

Text color is normal #FFFFFF, Home/Publish pages are normal, & Preferences & other windows are also normal (I have not checked everything, though).
