Title: The bar at the top of the Forum page seem to have a gap between the bar and the top of the web page (I think this is very likely a CSS issue).
Description of bug: When you scroll down or up the page you can see the contents of the page between the small gap.
When it started happening: I only noticed it just now so I am guessing today at some point.
Screenshots and videos of the bug:
Steps to reproduce the issue: All I do is just scroll and you can see the gap in the top bar. Unsure really how else to explain how to reproduce the issue cuz it just seems to be there.
