Well that certainly is an edge case scenario.
I would hazard a guess that it ... should be possible to get it working through another way of setting up WINE/Proton, if you can get all the dependencies and specifics figured out... maybe via Bottles?
But, figuring all that out would be a hassle, and may just end up not working.
I mean, if it works, it works.
The closest thing to that that I can say is that via RetroDeck on Bazzite, on a Steam Deck, I literally accidentally discovered that the touch screen controls for that worked just fine, without me doing anything beyond normal RetroDeck setup.
Just got annoyed, assuming that I couldn't use a DS/3DS second screen as a touch screen, 'Boy I sure with is could just-' .. and then I poked it, and then it worked.
But thats probably a different ballpark than getting an windows program to play nice with a linux touch/pad/stylus.
