Fix Version/s: None
0.4.10-RC-30-g51a70dc gcc dbg linux.
MkvToolnix 10.0.0.0 from rapps, the main app "MkvToolnix GUI" renders the text poorly in the sidebar. E.g. the word "Multiplexer".
The bug has not been introduced by the font metrics changes, it existed also before, but until now I found it to be too subtle to even mention it. But ros is constantly improving, so my nitpicking must improve as well.
