Start by reviewing the attached steam-563840-steam-deck.log and steam-563840-5900x-5x600xt-proton703.log, then reproduce the black-screen launch failure with Proton 7.0-3 on the listed systems. Done means identifying the compatibility cause and confirming a working launch, but the report does not name a source file, test, or implementation entry point.
