I'm having trouble in one scene with a camera whose focus target (supposed to be visible when adjusting focus_Distance) is either appearing above where it should (rather than centered in the view) or not appearing at all (which I'm guessing is just so high that it's not in the viewport at all). Depth of field is still working, it's just really hard to adjust this way.

I know this gets messed up if the Scale settings for the camera are not 100%, but I've checked those settings and they are normal. What else might cause the focus target to appear in the wrong place or otherwise not work properly?
