Dark Theme interface problems

@MisterMakerNL FYI

Wonder if this is caused by qtstyle.
Because I have not seen this issue in windows 10.

It's better on Linux, but it's like the headers in the settings aren't quite in their proper places anyway

There are definitely some tiny adjustments needed, to make it perfect.
It should eventually look exactly like no-stylesheet:

Btw in my new pr I set Qtstyle to fusion because to get a good UI it is nice that everyone is using settings.
I also think normal users won't notice any difference so having different styles won't do anything but cause lot's of weird bugs.
