What happens when a direct reflection point (sound from monitors) is glass (typical house window or even glass doors)? Does glass reflect the same, more, or worse than typical drywall house.. What is the best way to deal with this situation?

Sound bounces off it. right at you.

Depends on the glass and the drywall! Assuming you are talking about typicial studio glass and typical studio drywall, then: Glass is hard, stiff, dense, flat and smooth, so sound bounces off it quite well, higher frequencies better than lows. Drywall is similar, but a little "softer", less dense and less stiff, so the effect is a little less. But the difference is not huge.
What is the best way to deal with this situation?
Put absorption in front of the glass, at least a couple of inches thick.
