Hotfix release:

GE-Proton11-9

Video Playback

• Added a fix for Crimson Desert getting stuck after selecting Play or starting a new game due to

looping menu-video playback. Affects both Wine-Wayland and XWayland.

Rendering and HDR

• Added automatic HDR detection for DX11/DXVK and DX12/VKD3D-Proton with Wine-Wayland or Gamescope.

• PROTON_ENABLE_HDR=1 and PROTON_USE_HDR=1 are no longer required. HDR must still be enabled in

the desktop or Gamescope.

• Corrected a Wine-Wayland detection regression that incorrectly reported HDR displays as SDR,

affecting Dragon's Dogma 2 and other games on compositors without optional Windows-specific color-

management extensions.

• Preserved SDR fallback when HDR is unavailable or disabled.

• Retained legacy HDR overrides. Use DXVK_NO_HDR=1 to disable HDR reporting.

• Updated the README with automatic HDR setup instructions.
