Subject: [PATCH] Refresh tile previews on every overlay show
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cached CGImage from the previous close was being painted as
hasRenderedFrame=true, which short-circuited snapshot() on the next
show — so the user saw a stale frame until the live stream's first
significant-change frame arrived (or forever, for idle windows). Drop
the short-circuit so snapshot() always captures a fresh image, kick
off snapshot+stream in parallel with the show animation instead of
waiting 210ms, and stop gating the display path on the dirty-rect
threshold (keep it only for the idle-dot signal) so the tile keeps
tracking the source as frames arrive.
