## Summary
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.
