Graphics issue - icons overlaying entities in vanilla Java version

I’m noticing some strange graphics issues since the 1.21.6 update. So far I’ve noticed this on the sun and on maps, but there could be other things effected. Essentially, I’m noticing icons of other elements on top of the sun and maps (see screenshots).

The sun is normal looking in the middle, but it’s surrounded on top and bottom by miniature versions of all the different moon phases. It looks blurry in the screenshot because it has the vibrant visuals in the screenshots, but when I’m playing it looks perfectly clear (see picture I took of my screen using my phone’s camera - the diagonal marks are anti-aliasing from the photo of my computer screen and not actually visible in the game)

Maps have all these map icons on top, completely obfuscating the terrain on the map. Also, the little icon that moves around on the map showing where I currently am is not appearing.

I don’t have any mods or resource packs or anything like that.
