Title. There are several places, mostly in the last area leading up to the Exarch fight, where an invisible texture gets between the camera and your avatar, and it prevents you from targeting mobs, looting, and clicking panels.

You suffer this the most in the second room where mobs keep spawning until you can loot the droids. It's very difficult sometimes to find an angle that will allow you to loot the droid, then you again have to spin your camera around to click the panel. If it takes too long to do either, loot or use the panel, mobs continue to spawn. Very annoying.
