2026-08-24fix(graphics): batch kitty image row lifecycle (#3166)Can Celik
* fix(graphics): coalesce terminal kitty placements A Unicode-placeholder image arrives as one placement per viewport row it covers, and after 624dfd47 the budgeted encoder emitted one placement per frame, so every redraw painted images one row per frame. * fix(graphics): coalesce only pure kitty re-displays Keep pixel uploads and superseded-image deletes in a transaction of their own: a placement joins the coalesced transaction only when its image is uploaded and its source already maps to that image, and nothing joins after an upload or a delete. * fix(graphics): batch kitty image row lifecycle --------- Co-authored-by: kataokatsuki <kataokatsuki@users.noreply.github.com>

2026-07-04fix: kitty graphics streams freeze on partial updates and leak host images ↵Gabriel
(#948) * fix: request a render on kitty graphics writes pty output containing a kitty graphics sequence only scheduled the deferred settle render. that render's wake-up notifies the render loop only when the dirty flag was not already set, so under a continuous stream of image updates the notify can be dropped and the pane keeps showing an old frame until something else forces a full render. request an immediate render like any other output. the dirty flag and the minimum render interval still coalesce chunked writes, and the settle render stays as a backstop. refs #947 * fix: fingerprint kitty images exactly across retransmissions the image fingerprint hashed only the first, middle, and last 4096 bytes of pixel data. a program that streams updates by retransmitting one image id keeps the length and dimensions constant, so a frame whose changed pixels all fall outside those three windows gets the same fingerprint as the frame before it. the encoder then treats the image as already uploaded, emits no graphics bytes, and the frame is dropped as identical to the previous render. the pane stays stuck on the last uploaded image until a resize resets the graphics surface. hash the full payload instead. to keep that off the render hot path, cache the fingerprint per image id and recompute it only when the image's transmit time changes. libghostty-vt already refreshes the transmit time on every transmission; vendor patch 0002 exposes it through a new GHOSTTY_KITTY_IMAGE_DATA_TRANSMIT_TIME_NS accessor. a static image costs one map lookup per render and a streaming image one hash per transmitted frame. refs #947 * fix: delete superseded host kitty images host image ids derive from image content, so a pane image whose pixels change maps to a new host id on every update. nothing deleted the host image it replaced, and a streaming pane left one full-size image behind in the host terminal per changed frame until the graphics surface was reset. track which host image backs each pane image and delete the replaced one once no source references it. refs #947 * fix: prune stale kitty graphics source entries a source entry whose pane closed or whose placement disappeared stayed in the cache forever. through the shared-reference check it could keep an old host image alive that nothing visible used anymore, and the entries themselves accumulated without bound. prune sources against the visible set at the start of every encode pass. refs #947 * docs: link issue and upstream discussion for vendor patch 0002 the transmit time accessor now has a removal path: the ghostty discussion proposing it upstream is linked in the patch ledger. refs #947 --------- Co-authored-by: Can Celik <ogulcancelik@gmail.com>
