Mouse issues on older games (piefed.zip)

Hey there,

I recently purchased Tron 2.0 at GOG. Installed and launching it effortlessly with heroic. But the mouse flickers like crazy.

I do find a guide regarding the Steam version and so on. But I cannot find anything to replicate with the heroic launcher.

Does someone of you have experience with mouse issues on older games and knows more than me (probably yes xD)? I'm not thaaaat long a Linux user. Any help would be appreciated :)

I guess I need to put it into game argument? That did not work :/…

put it as environment variable in game's settings in heroic. https://github.com/Heroic-Games-Launcher/HeroicGamesLauncher/wiki/Environment-Variables

this of course only works if you're using proton AND wayland (EDIT: regular valve's proton doesn't have this, btw. only some souped up forks, like proton-ge)

Put wayland on and proton 9 beta. Works now. Thanks a lot!
