I've had units' movement/attack orders display when I don't have them selected and when I'm not holding Shift. Ctrl-U has no effect on this either. In the ChronoCam it may be because during a moment in the game I had those units selected? When I go back in the ChonoCam and press Ctrl-U, those orders remain visible. Also HP bars don't disappear - this is partly distance triggered, and also occurs when Fabbers are building/Assisting (disappearing when units Roll-Off). Here's what I'm seeing: Unit Icons (range-triggered), Green Metal Spot Icons, Planet Orbits and North-South markers also don't disappear. I hope this gets fixed so I can take pretty screenshots for the Forums! Keep being awesome UBER
Yes there is such setting in "UI" tab. It's disable everything what doesn't look natural in game world. It's mainly enabled by accident and then people complain about missing UI elements.
