vnc-bridge.sh kept FreeRDP connected to krdpserver from the moment remote desktop started, so krdp captured and H.264-encoded every KWin redraw in software (openh264) with nobody watching: krdpserver 55-78% of a core, xfreerdp 16-27%, Xvnc 6-11%, with 0 clients on :5900. krdp 6.7 creates its screencast session per RDP connection and drops it when the connection closes, so krdpserver itself idles without one and stays up. The bridge now counts established connections to Xvnc's port with ss, starts FreeRDP when a viewer appears (the desktop shows about 3 s later; the VNC screen is black until then) and stops it 45 s after the last one leaves (VNC_IDLE_SEC). Xvnc has no client hook, so its log output, which it writes for every connection, wakes the bridge early; otherwise it looks every 5 s while idle (0.1% of a core measured, against 0.9% for ss once a second) and every second while FreeRDP runs. The layout check runs only while FreeRDP runs. While a viewer is connected the bridge sends "watch 15" to ft-screens (@ft_screens) at once and every 5 s, so screens at a reduced frame rate (out of view, headset on a stand) stream at full rate; it lapses by itself if the bridge dies, and an ft-screens without the command just answers an error. The window search after starting FreeRDP now ends when FreeRDP exits instead of polling for 30 s. krdp on 127.0.0.1 with a fresh password, VNC on the tailnet address with VncAuth, and remote-ctl.sh start/stop (pause and resume) are unchanged.
