Yeah, Podman is definitely one of those things I would say to do the latter with. It’s functionality is the same as Docker though (commands work almost 1:1, and even docker-compose works with Podman), it has better integration with other system components (like automatically creating systemd services to start containers when a computer is restarted), and it gets you away from Docker as a company while still being able to access their containers on Docker Hub.
In the end though, I’d recommend sticking to what you’re familiar with. It’s always better to administer commands to your server that you know will work rather than learning as you go and hoping something doesn’t break.
I remember managing to get this issue solved on my computer. Looks like a QT issue. I may not remember exactly how I fixed it, but try the solutions in this thread and see if it works: https://lmms.io/forum/viewtopic.php?t=34104
In particular run
export QT_AUTO_SCREEN_SCALE_FACTOR=0
and then run LMMS from the same terminal.Also in response to other comments, LMMS is actively being worked on (though updates have been slow) – the last commit on the master branch was from 3 days ago, so that suggests that the project isn’t abandoned but development’s just rolling slowly.
