Symptoms

RPG Maker MZ only works on this old version of Proton (4.11-13) and only exclusively if you use beta version 1.0.2 or 1.1.1 of RPG Maker MZ.
I would like to see it running on version 6+. I want to make sure that it is given attention so it can be used in up to date versions.

There is a small issue that when running a playtest it gives an error: "Failed to initialize graphics". Otherwise MZ is completely unusable in all other versions of Proton.

Reproduction

Download RPG Maker MZ and try and run it with any other version of proton. it failed to run and crashed prematurely for me.
