Please supply precompiled and packaged proton versions.
I have an issue with windows losing focus post Proton-5.0, but frankly...after using Glorious Eggrolls packages and being able to just drop them into compatibilitytools.d... the need to jump through compiler and docker hoops half a dozen times before I can even begin to isolate where the issue first appears in mainline Proton is making me reconsider if it's worth the effort.
