Chunky anti-aliasing across macOS desktop client

Around a month ago, I noticed SVG shapes throughout the macOS desktop client started having this chunky, unpleasant anti-aliasing around the edges, which wasn't fixed by restarting, reinstalling, or changing zoom levels.

Visible on the Discord and server icons:

Visible on default emojis… inconsistently? (first is fine, last two have it)

Inconsistently visible in emoji reacts also. (Good, bad, good, bad)

I haven't noticed it in any other macOS apps, and the browser client renders these fine, which makes me think it's not a system-wide issue.
