## Summary
GloriousEggroll released GE-Proton 11-11, a hotfix addressing regressions from the 11.x series. The update fixes Easy Anti-Cheat "Violation 8" errors that blocked Star Citizen since 11-7 and Hunt: Showdown when launched outside Steam. It also resolves three separate MPEG-1 video playback issues causing freezes, upside-down rendering, and heap corruption in affected games. Additional protonfixes cover .NET 4.8 installation for Star Citizen's new launcher, mod loader support, and Windows version handling during winetricks operations.

## What GE-Proton 11-11 fixes
- **Video playback**: Resolves deadlock in MPEG audio decoder when skipping/closing videos with MPEG-1 audio via DirectShow (regression since 11-8)
- **Video playback**: Fixes AMStream MPEG-1 videos rendering upside-down (regression since 11-1)
- **Video playback**: Fixes heap corruption from converted/scaled video frames, resolving crashes in games like Target Bravo: Operation G.H.O.S.T.
- **Anti-cheat**: Fixes EAC "Violation 8 - Untrusted system file" for Star Citizen (since 11-7) and Hunt: Showdown; VKD3D-Proton stops reading parent process executable for Unreal Engine detection
- **Protonfixes**: Re-applies Windows version fixes after winetricks changes to prevent stuck Windows XP prefixes; adds .NET 4.8 for Star Citizen's RSI Launcher; fixes for BepInEx, MelonLoader, FrostyModManager mod loaders

## Why it matters
The EAC fix restores playability for Star Citizen, a high-profile title with significant Linux user investment, and corrects a broader VKD3D-Proton detection method that could affect other Unreal Engine games. The video regression fixes address stability issues that had persisted across multiple 11.x releases.
