Some games don't handle 32-bit sized joystick axes well. Assetto Corsa Rally, which was released a month ago as an early access and is still v0.1, is a recent example. The proof of concept 16-bit patch resolves the problem for many users and hardware on Linux, (https://github.com/ValveSoftware/Proton/issues/9220#issuecomment-3647591465) and users with open-source hardware confirmed the behavior of the game on Windows. Since it's the case that the game is non-compliant while the wine is perfectly compliant, we might be able to push and wait for the developer to release the fix, but I believe that the fix will also help to improve compatibility for some old, non-maintained, non-compliant games. -- v3: winebus: Use smallest report size for unsigned axis too https://gitlab.winehq.org/wine/wine/-/merge_requests/9789
