Proton Wineland wurde in der Version 11.0-20260908 veröffentlicht.

Proton Wineland ist ein Fork von Proton-CachyOS, also eine Kompatibilitätsschicht zum Ausführen von Windows-Spielen unter Linux mit zusätzlichen Patches und Optimierungen.

Die Version basiert auf cachyos-wineland-11.0-20260713.5-slr und stellt auf wineland-*-Tags um. Neu sind unter anderem OptiScaler-Nightlies über PROTON_USE_OPTISCALER=nightly, die automatische Auswahl des primären Monitors unter KDE, GNOME, niri und COSMIC sowie eine unabhängige Cursor-Skalierung per PROTON_WAYLAND_CURSOR_SCALE. Zudem wurde die DOOM-Eternal-Regression mit schwarzem Fenster behoben und Wine Mono auf 11.2.1 aktualisiert.

New features and improvements

• OptiScaler nightlies: Use PROTON_USE_OPTISCALER=nightly for the latest official nightly, or pin a version with PROTON_USE_OPTISCALER=nightly-20260906. Downloads are verified before installation, with rollback on installation errors. PROTON_USE_OPTISCALER=1 continues to select stable releases.
• Initial monitor selection: Proton now reads the configured primary monitor on KDE and GNOME, the focused output on niri, and COSMIC’s preferred display for X11 games. COSMIC’s preference is also used for native Wayland games. Explicit WAYLANDDRV_PRIMARY_MONITOR overrides remain respected. Unavailable or ambiguous results leave the default unchanged.
• Independent cursor scaling: PROTON_WAYLAND_CURSOR_SCALE=2 doubles the size of Wine bitmap cursors without changing game resolution or mouse sensitivity. Fractional values are supported. This does not resize cursors drawn directly into the game image or cursor shapes controlled by the desktop.
• HUD improvements: Updated fonts, larger main text, smaller information rows, complete units, and configurable translucent backgrounds covering each text block. Extra options can now follow a preset.

Wineland fixes

• DOOM Eternal: Fixed the .5 regression where the game could open with a black window.
• DXGI compatibility: Added the missing CompatValue export expected by some games and mods, without enabling undocumented compatibility overrides.
• Multiple presenters and vkd3d-proton: Various cleanups.

Bleeding edge cherry picks

• Steam integration: Added Steamworks SDK 1.65 support, corrected networking message layouts between 32 and 64 bit code, and avoided unnecessary environment updates in the Steam client bridge.
• Launcher compatibility: Added recognition of steam2ea:// links, corrected acknowledgement event permissions, and exposed Steam’s appcache directory inside the prefix.
• Audio: Fixed WMA decoder initialization and added DirectSound conversions from mono, stereo, quad, and 5.1 sources to 7.1 output.
• Fonts: Added Lucida Console and Microsoft YaHei Bold replacements, including the font needed by Souper Game, and updated Source Han Sans to 2.005.
• Wine Mono: Updated to 11.2.1.
• X11 presentation: Fixed child-window presentation beneath an exclusive fullscreen window. Native Wayland presentation is unchanged.
• Build system: Corrected linker flag propagation to Meson projects.
