For a while I couldn’t even install osu! because of font issues as far as I know, but it’s been fixed a bit ago and now I can install it, but if I switch to using wine-osu then I have very bad sound and performance issues. The game seemingly randomly speeds up and down, and the sound is really weird, like it’s cracking a lot.
With wine 6.21 it runs “normally”, the maps take a few second to load every time, and I can’t login, but I don’t have the issues mentioned with the osu specific wine.
I’m using pop os 21.10 but it was working on arch, and I had no issues with it!
I don’t know if there is even fix on ubuntu/debian
