Version 80.0.3950.0 (Developer Build) (64-bit) looks fine for me (on topic)
My theme is light, yours is dark: is it an extension or part of Discourse?
Hmm, seems to just be an issue with the dark theme. Tried on Chrome, Edge (Chromium), Firefox and it affects all. All browsers latest stable builds. Changed to light theme and that seems to cause it to vanish. However changing back to dark theme causes the issue again. (Disabled all browser extensions incase those could have caused it)
