Something is wrong with lyric font kerning in 2.03
Musescore 2.03 seems to add extra space with some letters in lyric text, that would make them difficult to read.
This is an example from 2.03
This is what it looks like in 2.02
Actually, the same characters look a little squashed in 2.02, just acceptably so. So I'm assuming you guys did a fix, but just bumped it a little too far and it can be easily fixed in next build.
