Moonshine, a headless streaming server for Moonlight, has been released in version v0.16.0.

Highlights include clipboard paste from Moonlight clients with Unicode support, native touch and pen input, and a low-latency mode for Vulkan video encoding. The release also brings a range of fixes around Steam overlay, Wayland focus, AV1 encoding and the Heroic Games scanner.

Added

• Implement clipboard paste from Moonlight clients, including Unicode text.
• Add native touch and pen input. (#175, @antomanc)
• Use low-latency mode for Vulkan video encoding. (#180, @KarlVogel)
• Expose the external port in the server info response. (#196, @BigDiaB)

Changed

• Index icon directories once when resolving box art, removing a full recursive filesystem scan per application that froze startup. (#205, @mozvip)

Fixed

• Cache color converters per input format, so switching render paths no longer rebuilds them every frame.
• Treat a client-hidden cursor as hidden when choosing direct scanout, so hiding the cursor no longer forces the GLES compositing path.
• Impersonate gamescope when launching Steam games so Steam uses its external-overlay mode, fixing the Steam overlay.
• Honor xdg-activation focus requests so Wayland-native games (e.g. Proton with PROTON_ENABLE_WAYLAND=1) get keyboard focus instead of the Steam UI keeping it.
• Hold the focused game window at the output size regardless of its fullscreen hint, so games running below the stream resolution are scaled up to fill the output; dialogs and overlay windows keep their own size.
• Request an IDR frame when an encoded frame overflows its bitstream buffer, so the next frame is a keyframe and the client’s reference chain stays decodable.
• Wait for the render fence before handing a frame to the encoder, so the encoder no longer reads a stale buffer from the round-robin pool and frames arrive out of order.
• Bump pixelforge to v0.9.1, fixing AV1 encoding.
• Give the systemd start job a fixed 90-second timeout decoupled from launch_timeout_secs, so a configured pre_command isn’t cut off.
• Reject resume requests for stale sessions so Moonlight no longer waits for a reconnect that cannot produce frames. (#185, @brongan)
• Tolerate audio clock timerfd wakeups with no expirations instead of tearing down the session. (#167, @lutyjj)
• Drop a PulseAudio client that stops reading instead of letting its outgoing buffer grow without bound and crashing the session. (#184)
• Don’t advertise a default PulseAudio source name, which crashed some native Linux games. (#173, @KarlVogel)
• Return an empty string instead of null for the PulseAudio source, fixing a crash in Factorio. (#198, @KarlVogel)
• Make application IDs positive so they are accepted by the Moonlight web client. (#197, @BigDiaB)
• Ignore the null and unmapped keyboard packets some clients send for touch input, which previously flooded the logs. (#175, @antomanc)
• Disable nixpkgs’ bundled services/networking/moonshine.nix from the NixOS module so it can be enabled without conflicting with the upstream module. (#187, #190, @amateurattentionseeker)
• Read GOG install state from Heroic’s gog_store/installed.json, which Heroic strips out of the library cache, so the Heroic scanner no longer skips every installed GOG game. (#169, @scottjab)
• Prefer Heroic’s cached cover art over its shortcut icons, so GOG games no longer show a small square store logo as their box art. (#169, @scottjab)
• Warn when the Heroic store cache cannot be read. (#169, @scottjab)
