To fix this (with the sunroof and shade completely closed), I pressed up on the sunroof button and held for 2-3 minutes. After a while, everything opened all the way, and then closed all the way. This was its calibration procedure.

I believe the same applies to the windows - if you somehow lose the calibration data, it'll get upset, and a similar procedure will re-calibrate it.
Wow, interesting! Somehow doing an SG_RESET on the whole car didn't mess up my windows or sunroof at all, but good to know, thanks for the heads up.
