If I play the 5th fret on the B string and an open E, I can tune that interval perfectly. However, when I play an open G string, and third fret on the high e (an octave), my E string is about 20-30 cents sharp. If I tune the G string to match the octave I just played, then when I play the 4th fret on my G and an open B (unison) the B string will be out of tune.

Does anyone know what's going on here? My intonation at the 12th fret is fine, for reference

The G is always kinda whack. Intonation will never be perfect on a guitar with a straight bridge and frets. I've even played some high end Martins where the G is terrible.

Yours might do with a little bit of adjustment but it's something most players learn to work around.
