GE-Proton 11-11 hotfix patches video regressions, EAC anti-cheat issues

GE-Proton 11-11 is a hotfix release addressing bugs in the community Proton fork used to run Windows games on Linux. It resolves video playback regressions dating back to GE-Proton 11-1 and 11-8, plus an Easy Anti-Cheat compatibility issue affecting Star Citizen and Hunt: Showdown since 11-7. The release also includes Protonfixes for mod loaders and specific games.

What GE-Proton 11-11 fixes

• MPEG-1 audio deadlock: Fixed games freezing when skipping or closing videos with MPEG-1 audio via DirectShow; regression since GE-Proton 11-8 (issue #865)
• AMStream video orientation: Fixed MPEG-1 videos displaying upside-down via AMStream; regression since GE-Proton 11-1 (issue #863)
• Heap corruption in video scaling: Fixed crashes from converted/scaled video frames, notably Target Bravo: Operation G.H.O.S.T. stage select crash (issue #864)
• EAC false positive: VKD3D-Proton no longer reads parent process executable to detect Unreal Engine games, fixing "Violation 8" kicks in Star Citizen and Hunt: Showdown (issue #858)
• Removed incorrect fix: Reverted Star Citizen native AMD AGS override from 11-10, which was not the actual EAC cause
• Protonfixes updates: .NET 4.8 auto-install for Star Citizen's new RSI Launcher, Windows version re-application after winetricks installs, BepInEx/MelonLoader/FrostyModManager support, Call of Duty (2003) fix repair

Why it matters

The rapid hotfix cycle reflects GE-Proton's role as a bleeding-edge complement to Valve's official Proton, though users are reminded that Valve's build remains the recommended default for stability. The EAC fix is particularly notable for multiplayer titles where anti-cheat compatibility determines Linux viability.
