Linux Mint 20

Behavior

Some (not all) of the number inputs (i.e. the textboxes with the | - | + | buttons on the right) are cut off. Notice how it is cut off on Solid layers, but not on Perimeters

Project File (.3MF) where problem occurs

Not relevant.

I'm happy to do additional debugging, trying out stuff, or work on a fix. Never had a look at code base yet, so a bit of guidance would be very much appreciated.
