A backgrounded but still-attached emulator kept the frame stream running: continuous WebCodecs H.264 decode + ctx.drawImage (Android) or Blob + createObjectURL per MJPEG frame (iOS) painted to a visibility:hidden canvas, with frames still flowing over IPC (and the network for paired SSH/remote clients) to no viewer. This stacks per open worktree holding a live emulator. EmulatorPane already threads isActive (it gates autoAttachOnMount) but never passed it to EmulatorDeviceFrame, so showStream gated only on isLive. Gate it on isActive too. The overlay slot already sets visibility:hidden when isActive is false, so this can never blank a visible stream. The session stays attached (autoAttachOnMount untouched), so the stream re-fires within a frame on re-show via the existing enabled effect. Mirrors the browser pane's park-when-hidden. Both stream hooks tear down on disable: useEmulatorVideoStream stops the H.264 forwarding at the source (stopVideoStream) and closes the decoder; useEmulatorFrameStream calls stopFrameStream and revokes the Blob URL. Test asserts the IPC contract (not just DOM): no startFrameStream while the pane is inactive, and stopFrameStream on hide. Reverting the gate fails 2/3. Co-authored-by: Orca <help@stably.ai>
