The 3D mouse drives SteamVR's laser through the ft_pointer virtual controller, so its events reach the screens the same way a controller's do. The filter held every press, which turned the mouse's short drags (selecting a character or two, nudging a slider) into clicks. Mark button events from hand controllers and start the filter only on those. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
