Atlassian Support wasn't able to recreate this, but I have users experiencing it (Windows 10 & 11 and in Edge and Chrome).
When opening a ticket, from filter results only, the internal vertical scrollbar is incomplete. I can't see the bottom of it. This doesn't happen from a queue, or when you do a single ticket search - only when opening it from a filter. Other users have it happen where it is missing from the top.
Does anyone know why this happens?

Otherwise, it's fine:
