Sometimes when I change the screen size in my game, the camera seems to still think the center of the screen is still based on the old resolution. Restarting the game fixes the issue - as my game loads the last saved resolution on starting, but it would be nice to not have this problem.

I could not find anything in the manual under Video_Set, or Video_Switch that might explain this behavior.

Has anyone encountered this before?

It use to be the effect of not resizing the whole rendering chain. Do you use pp shaders?

Ah, that might be the problem! Yes, I am using a few of them.
