dwproton 11.0-16 Fixes NIKKE Video Playback and Arknights: Endfield’s Launcher

dwproton 11.0-16 targets two practical problems for players running games through Proton: video playback errors in NIKKE and black bars around Arknights: Endfield’s launcher. The update also refreshes Proton and its components to a newer CachyOS build, giving this release a broader compatibility update alongside its game-specific fixes.

Two targeted fixes for game startup and playback

The NIKKE fix restores a patch for video playback errors when the game runs through umu-launcher. That distinction matters: the changelog identifies the affected launch setup, rather than claiming to resolve every possible video problem across all configurations. For players who encountered playback failures in that environment, the patch is the update’s clearest direct improvement.

Arknights: Endfield receives attention at the launcher stage. The update improves the launcher’s rendering so it should no longer display black bars around its window. It also forces winex11 for the launcher when the game is installed through Epic Games. These are separate adjustments aimed at how the launcher appears and which graphics path it uses in that installation setup.

That focus on the launcher is useful because compatibility issues can show up before a game reaches its main interface. A launcher that renders poorly can make starting or managing a game less straightforward, even if the game itself is the main reason someone installed the compatibility layer. The changelog doesn’t claim a change to Endfield’s in-game performance, visuals or gameplay, so the reported benefit is specific to the launcher.

What the component refresh means

dwproton 11.0-16 updates Proton and its components to cachyos-11.0-20261015-slr. Proton translates the Windows features games rely on so they can run in Linux environments, including Steam Deck’s SteamOS. Refreshing its components can change how particular games behave, while the two named fixes in this update show where the maintainers have called out specific results.

For players, that means the version number alone doesn’t tell the full story. The useful details are which games and setups the changelog names, and whether those match a player’s own installation. Here, NIKKE’s video issue is tied to umu-launcher, while the winex11 adjustment for Endfield’s launcher is explicitly tied to Epic Games installs. Players using other launch methods may still benefit from the component refresh, but the changelog doesn’t specify additional game-by-game changes.

Nor does the update provide performance figures or a list of hardware tested. Its stated improvements concern playback and launcher rendering. Anyone comparing behavior before and after updating can focus on those concrete symptoms: whether NIKKE videos play under the named setup, and whether Endfield’s launcher window renders without the reported bars.

Getting the update on Steam Deck

The article says dwproton can be downloaded through ProtonPlus, which is available from the Discover Store in Steam Deck’s Desktop Mode. That gives Deck owners a route to install the compatibility layer outside the usual game library view. The update is identified as dwproton 11.0-16; players should select that version through their chosen installation method if they want these specific changes.

There’s a practical distinction between installing a compatibility tool and changing a game’s launch configuration: the update supplies the Proton build and its fixes, while the reported winex11 behavior applies to Endfield’s Epic Games launcher installation. The source doesn’t describe extra setup steps, so it’s best to follow the options presented by ProtonPlus and the game’s existing configuration.

A focused update with clear targets

The full dwproton 11.0-16 changelog lists three changes: the CachyOS-based Proton component update, the restored NIKKE playback patch for umu-launcher, and the Endfield launcher rendering and winex11 adjustments. It credits MrLGamer for the launcher rendering improvement.

For Steam Deck and Linux players, this is a small update with specific, player-facing goals. NIKKE players using umu-launcher have a playback fix to try, while Endfield players on Epic Games get launcher adjustments aimed at cleaner rendering and a forced graphics path. The next useful signal will be whether those changes address the reported issues in players’ own setups; the changelog makes no broader claims about compatibility or game performance.
