Disabling peak detection (efb0e885) did not stop the per-frame shader LUT regeneration on Snapdragon devices: libplacebo keys the tone-map LUT on the frame's raw HDR metadata, and mpv forwards HDR10+ per-scene values (scene_max, scene_avg, ootf) on every decoded frame, so the LUT - at tens of milliseconds per rebuild on Qualcomm's D3D11 driver - still regenerated continuously and playback kept stuttering and flickering (#2191).
Zero the dynamic metadata before the renderer with vf=format:hdr10plus=no on Qualcomm GPUs; tone mapping uses the static HDR10 mastering metadata and the LUT is generated once. Dolby Vision L1 metadata is deliberately not stripped: dovi=no would break profile-5 rendering. The applied HDR pipeline options are now reported into the app log on first file load so uploaded logs are self-diagnosing.
