Note that if the two sides of the glass at entry and exit are not exactly parallel, then the heading does change.
A curved glass airplane canopy does change the heading a little bit because it isn't flat. The entry point and exit point are not parallel.
Also, even if a glass pane is flat, there are tiny imperfections or undulations in the surface that make it not perfectly flat, so there is some distortion possible. But it is usually so neglible as not easily noticed through casual observation. For the most part, looking through a modern window produces an undistorted view.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
