Staves in 'Create time signature' dialogue are badly laid out
S4 - Minor
OS: Ubuntu 18.04.3 LTS, Arch.: x86_64, MuseScore version (64-bit): 3.3.0., revision: 3543170
This is most noticeable in dark mode.
I'm guessing this relates to screen resolution, on my system it looks OK (vertically off-center still, but not cut off).
BTW, there's no good reason we need to much whitespace above the staff, I guess we are honoring the music top margin or something like that.
I ended up applying a fix for this as part of https://github.com/musescore/MuseScore/pull/5480. I'm not sure it's a 100% correct fix - it still relies on some hard-coded constants - but at least they are being scaled correctly in my PR, so it has a better chance of working on different resolutions.
