(3) Please note, this is a custom build of proton, and is -not- affiliated with Valve's proton. Instead, contact me on Discord about the issue: (2) If you have an issue that happens with my proton-GE build, provided FROM this repository, that does -not- happen on Valve's proton, please DO NOT open a bug report on Valve's bug tracker. If you want proton functionality -outside- of proton for non-steam games, I provide Wine-GE for usage with Lutris, found here: It may work, if enough libraries match, but it is not correct and not supportable due to library differences across distros. It causes wine to search for libraries on your system instead of those it was built with/intended for within proton.

Not running it as intended results in the container and therefore its runtime not being used, and severely breaks library compatibility. Proton runs in a container, which uses a runtime environment and libraries specifically built for use within that container. Proton-ge-custom (1) RUNNING NON-STEAM GAMES WITH PROTON OUTSIDE OF STEAM IS NOT SUPPORTED.
