Yeah, adjusting the camera angle is an important feature. It really helps to see things that are blocked by other objects, even with the ghost outlines that a lot of games like to use.
Seen that with quite a few older games. Was pretty annoying when playing on newer versions of Windows as the notification feature would often trigger the weirdness, requiring either a restart of the game of alt-tabbing to bring back the focus lock. The method varied from game to game. It may have had to do with some focus lock features missing back then in Windows as it was so prevalent.
