What is the white stuff? Never owned or used a dishwasher in my life so wouldn't know.
If it's stuff similar to limescale steeping them in vinegar will get rid of it.
It is an opaque patina, and it is actually just aesthetic. The glasses are perfectly clean.
Rice, how should I use the vinegar? Soak the glasses in vinegar? Wipe them with a vinegar-soaked cloth?
By the way, I walked by your place today and I think you were home, because I saw the window open. It was about 6:30PM!
