wallr 0.8.3

highlights

• static image fill mode now center-crops to the output before shared-memory presentation when the source covers the display, avoiding unnecessary gpu promotion.
• shared-memory buffers stay bounded, support short switch bursts, and are reclaimed after activity settles without periodic polling.
• benchmark scripts support dynamic ffmpeg by default and optional static linkage. They verify the binary linkage and include it in reports.
• added a helper for preparing the pinned static ffmpeg toolchain used by linux release builds.

validation

• formatting, workspace checks, clippy, release build, and all 100 tests passed locally.
• the tagged linux release workflow passed, including static ffmpeg hardware-support checks, self-contained daemon verification, and archive validation.
• the local wallpaper benchmark and decoder measurements are documented in the repository.
