Blurry AE UI?

I thought there was something wrong with my iMac's monitor or my eyes, but my AfterEffects 2021 UI is actually the culprit. The whole UI is blurry, as if someone had chosen the wrong setting somewhere. I assumed I was that person who used the wrong settings, but I can't find anything in preferences to help. Here's a screenshot of "Preferences" from the header of my preferences, just to show how things look on my Retina 5K, 27" monitor. If you look closely at the text palette that I've screenshotted, you can see how all of the T icons are soft around all of the edges, and the 00s are blurry enough that you can see them melting into each other where they overlap. These details are about the same size as the smallest type on this help webpage, which is clean and crisp.

Any ideas? Anyone else seeing this? It makes it really hard to see details in the UI, and being able to see tiny type and little icons is very imporant when you're using a complex program like AfterEffects on a big monitor. I can lean in and see the pixelization on icons and text. My actual renders and compositions are fine.
