As soon as a paragraph with wrapped lines exceeds the size of the text area (and the scrollbar is displayed), the view starts to flicker as soon as you continue typing. The scrollbar then also wobbles up and down.

This can be recreated with the RichTextDemo in the repo:

I would also be happy to try to fix the error myself if anyone has a tip on where to start after troubleshooting.
