Thanks, in that case the https://gitlab.winehq.org/wine/wine/-/merge_requests/4695 MR should fix the side buttons (4-5) for you.
You also mention mouse3 (=scroll button click, I assume the same as middle click?). Does that not work for you?
Thank you. That helped. Tonight I'll try out how wayland works in game. I didn't check the middle button because, now I don’t have any bindings for this button in games, but it’s the same thing as scroll click. I'll check later the middle button works or not and let you know.
