- Close: hide the window, dispose every player, thumbnail job and the
sound engine, leave, then close normally; Linux runner _exit (the
NVIDIA EGL exit handler crashed 10/10 closes, 0/41 now); Windows tears
down inside the message loop, then TerminateProcess; watchdogs.
- Version under the Settings tab; an update band instead of a dot,
never over a video; checks at start and every 4 hours.
- Chat pop-ups default to All again.
- Shader read-back compared as a list (old mpv joins with ','), so
Windows stops turning shaders off; Windows hwdec auto-copy.
- Render diagnostics (`mpv: render` lines); RAM-only demuxer cache pin
silences the file-cache warning; a volume readout test.
