@kittykat Is the timeline flickering just the display of messages or is it flickering between two different scroll positions?

Just the display of messages

Not sure if this is related, but I now have a room where I cannot scroll at all anymore. I can't go up to see the history and it also doesn't scroll to the bottom of the screen, so the last message hangs in the middle of the screen:

Closing and restarting Element fixes this particular problem
