Every configure the compositor sent during an interactive resize ran a whole frame inside Wayland event dispatch, including one at each stale intermediate size, so a fast drag queued more frames than the app could draw and the window lagged further and further behind. Configures and input now only enter the coalescing queue during dispatch; each frame applies the newest configure, acknowledges it and delivers the merged input, and the main loop waits for the compositor's frame callback before drawing again, so it renders at most once per display refresh. The synchronous refresh path is removed. Platform input is muted before the queue while tests inject theirs into it. Leo keeps every pointer sample so strokes stay smooth; other applications merge motion.
