Thank you for your comment, this is the first time to hear about this bug, I'll look into it! (Don't want to make any promises I'll be able to fix it though, I know less than nothing about Linux, sorry)
Tell me if there's any way I can assist you or give some feedback to make it work, if you want or need it.
In the mean time I tried the windows version through proton (Valve's compatibility layer). There are some graphical glitches and the controls are a bit inconsistent (especially when switching camera angles) but I could make it through with a gamepad. The camera angles are quite on the nose sometimes haha. A guy turning slowly into a girl I guess is a fantasy that can speak to me ¬‿¬
Nice job. Polishing it a bit more would be lovely.
