Hello @es20490446e, the majority of Proton is wine under the hood. If you have an issue with individual games where they work with upstream wine, but not Proton, please give feedback on the compatibility report of the individual games so that we can look into them.
There should be a key difference. Also it just makes more sense to report to Wine directly, and not having an intermediate silo.
