If I scroll quickly through a specific room's timeline with multiple videos in it, I consistently get the following error. I don't know if it's related to the specific videos, but it doesn't happen when I scroll slowly, maybe it happens if the video element is out of view before it's fully initialized.

A ValueNotifier<VideoViewParameters> was used after being disposed.
Once you have called dispose() on a ValueNotifier<VideoViewParameters>, it can no longer be used.
