These are some observations from before the server went down.

1. The icons were cropped in multiple places, differently.
2. emoji window cutoff in multiple areas, but visable part still usable
3. the entire left column "Settings" shifted in rendering, upon any scrolling in the right column feed; displayed jitter
4. the most unusual thing I saw was the row of user icons (dark mode, serch, user avatar) rendered in the bottom left column next to "Settings"; couldn't find how to replicate, but it persisted once- was prior to most recent update)
5. @mention windown cutoff (similar to emoji window)
