Turning off the interface elements (All Off) shows several bugs:
some elements never go away... examples:
-grapple icons always show
-binoculars button map interface icons always show
Some intermittent:
-While traversing the world, various text messages for new missions and such will pop up and stay on the upper or mid left, sometimes only one line of the full text will stay
-soldier names show when close up, sometimes dont... prefer they dont if ally tags are off
-interaction prompts seem to render one frame, then hidden the next, creating a blurry circle such as when falling (for the parachute prompt)
A QA tester with a couple hours time should catch most of the aspects of these bugs, doing a few missions and going around the world with the interface set to All Off
The game is beautiful and totally playable without the crazy UI clutter once you learn the pickups. Would be nice to be able to completely eliminate the GUI during gameplay without the bugs.
