Disconnected input cache and catch-up replay
Cache missed input for a disconnected follower and replay it after reconnection while other connected desktops continue syncing.
Updated October 8, 2026
Keep input caching enabled
This option is enabled by default in Sync control. Once live sync starts, clicks, keys and clipboard text are cached for a follower only after its disconnection is detected. Desktops not selected as followers do not receive synchronized input.
Wait for automatic catch-up after a short outage
Reconnection within 30 seconds with matching desktop dimensions starts catch-up automatically in the original order and timing. Check the cached-input or replay-in-progress status on that desktop. New input queues behind the backlog until it catches up.
Check the desktop when confirmation is required
Long outages, potentially incomplete operations or another disconnection during replay require checking the page first. Choose Replay when the current state is suitable. If windows or pages have changed, choose Discard cache and align them again. Stop replay is available while catch-up is running.
Know when the cache is cleared
The cache stays in the current page, limited to 5000 inputs and 2 MiB per desktop. Discard a full cache and align the desktop. Pausing sync, changing master, disabling caching, refreshing or leaving clears caches. Deselecting a follower clears that desktop’s cache.
Catch-up uses coordinates, cannot identify page buttons or wait for loading, and cannot confirm whether the last operation before disconnection succeeded.
