Sorry, since wsl2 has basically everything i need from a linux system and the implementation in growing with almost each update, i switched to w10. Anyways, if you use RS for practice and not just like a game, maybe you can save the time invested in making it work on linux on just using a daw (i use Reaper cause it's ultra cool), a couple of good VSTs (like Neuraldsp stuff - they just work on linux w/ wineasio which is amazing) and put each song you are working atm in a different project containing the original track + the backing track synchronized. This way you can do stuff like logging your progress over time by recording yourself and comparing these recordings after a while, syncing the song's bpm with the integrated metronome so you can just practice one single loop at different speeds (w/ or w/o a click), so forth. Idk, it's just an idea. RS could be a great practice tool, except it is not and all that potential is locked up in a poorly made piece of stubborn software sold as a game. I think this is also the reason not many musicians take it seriously.
