Lyric display changes spontaneously (and not for the better!) in open program
Lately, whenever Musescore sits around open for a few hours -- typically with a score open -- something happens that changes the display of lyrics. The font grows on the display or something. The lyrics are then smashed together, as in the screenshot "Fall (bad lyric spacing).png" below.
If I close and reopen Musescore, then reopen the same score, everything's back to normal (as in "Fall (good lyric spacing).png" below), but only for a while.
