After a take record within multi-user has completed recording, and with Toggle Multi User Take Recorder Sync enabled, any other control boxes with the ICVFX window open to UV view will flash with the material of each node output. This only happens inside the ICVFX window. Also, when a take record has started or completed recording, our render boxes have the possibility of hitching. Both of these issues only happen while Toggle Multi-User Take Recorder Sync is enabled. If it is disabled, neither issue persists.
