Symptoms

Launchig any of these games using the bleeding edge version of Proton Experimental causes the games to launch to a white screen (for No More Room in Hell and Fistful of Frags) or to a black screen (for Pirates, Vikings, and Knights II). This does not occur with the regular version of Proton Experimental.

OK. Proton Experimental (bleeding edge) just updated right now and the problem no longer seems to occur??? I guess we can close this issue?

Hello @Reikott, the bleeding edge build of Proton Experimental is automated and untested, sometimes odd quirks happen. Glad to hear it decided to behave for you. In general, look alike issues need to be evaluated on a per-game basis, so if something similar happens again, please add a note to the individual game's compatibility report(s) with logs.
