MuseScore 2.0.3 from Ubuntu PPA crashes on Linux Mint KDE 17.3 and 18
I have installed MuseScore 2.0.3 via
ppa:mscore-ubuntu/mscore-stable on Linux Mint KDE 17.3 and on Linux Mint KDE 18, on two different PCs. In both cases it works for a while, then it crashes. I have tried many times and the behaviour is always the same. Sometimes I observed severe file corruption too.
On both PCs (LMKDE 17.3 and 18) the AppImage version works perfectly, and on the 17.3 MuseScore 2.0.2 from the PPA worked perfectly as well.
Of course I could just use the AppImage version, but for many reasons I prefer using the PPA. Anybody could please help me?
