A switcher to replace a wlthumbs + rofi pipeline, with the same look (gruvbox, ceil(sqrt(n)) columns capped at 4, 16:9 tiles, a yellow selection filling the element padding) but no thumbnails anywhere. Each window is captured straight into a wl_shm buffer that is handed to its own wl_subsurface, with wp_viewporter giving the compositor the rectangle to scale it into. So there is no PNG encode, no scaler, no full-resolution bitmap in this process, and the capture buffers are never even mapped here — the compositor writes those pages and samples them again for display. Opens in ~65ms for 8 windows (55ms of which is the compositor reading pixels back out of the GPU) and holds ~9MB of RSS. All capture sessions are opened before a single roundtrip and every frame goes in flight together, the same batching wlthumbs uses, because the readback is bandwidth-bound rather than latency-bound. sway remains the source of truth: the window list, the con_ids and the focusing all come from its IPC socket, joined to the Wayland side by foreign_toplevel_identifier. Navigation reads raw evdev keycodes so it is layout-independent, which does mean virtual-keyboard clients that invent their own keymap can't drive it; that resolves when filtering brings xkb. Labels, type-to-filter and live previews are next.
