I was able to isolate some of these errors by using journalctl -f.
This one appears when no windows are present on screen:

I'm not sure about these, but they seem to appear even if I've been focusing on one window for a few minutes:

Context
The problem became apparent to me after installing and using UWSM, so I imagine it's just the program's regular output and only happens to be in the journal because of UWSM.
