I figure I might as well post bugs here as well, so that everyone else can potentially benefit from them if they see something similar.
Running SIS in windowed mode, I noticed some graphical artifacts in the starfield on the main menu and faction selection screen. They appear to be the outlines of the large stars in the background. The most noticeable one is at upper left. These only appear in windowed mode, not in full-screen mode.
