Musescore 3.6.2 doesn't work (most of the time) with Linux 20.04

• Mar 8, 2021 - 15:30

3.6.2 is sluggish, slow, and downright not operative. A very few of my pre-existing scores work without stalling or simply just sitting there, regardless of commands. I'm extremely lucky that I didn't delete my previous version (a 3.0 ). Too bad, because the new features in 3.6.2 are great.


Can you explain in more detail what you mean? Which Linux distribution, and what in particular is working slowly for you? Best to attach your score and give precise steps to reproduce the problem.

A new development. I'm not sure what I did, but I'll try to remember. I did some messing about in 3.0.5 with sound fonts, I/O etc. and nothing played. I hit the set to default button. Still no sound. Then I closed it, and when I re-opened, it asked me questions as if it were new and I hadn't set preferences. Everything worked well then in 3.0.5. So, I tried opening 3.6.2 to see what might have happened, and everything worked well. I tried three scores, and all went well. You might be able to figure this out, but I can't.

Near-instantaneous opening for me. No problems on moving the score, changing notes etc.

OS: Ubuntu 20.04.2 LTS, Arch.: x86_64, MuseScore version (64-bit):, revision: 3224f34

Quad-core Xeon, 16Gb RAM - but I've got other stuff running in three browsers simultaneously and a large spreadsheet open and HTOP reports only 6Gb RAM in use.

Maybe you have inadvertenyl loaded a large sound font, drumline or something else that I don't have loaded on my system.
