Hello,

I have the problem, that Mangohud and other things, that get pre-loaded with the Steam game launch options, just stopped working with recent Proton Experimental and as well with recent Proton GE versions.
The console output shows it is still loading, but stopping somehow.


This is Mangohud working with Proton-7.0-4
