It seem be be part of UMG and it floats like the rest of my HUD. It updates pretty much every frame and most if I move around. Some times it goes away for a while, but I can never tell when, might be connected deferent areas. Is it some kind of performance test thing?
I do have a SpringArm but I never really had a chance to try anything, because it just disappeared when I recompiled all my UMG widgets (at least I think that’s what did it).
It’s a total mystery still though, nothing in my HUD look anything like that.
