PS4 standard, playing splitscreen. Occasionally, for both players, item description boxes from the backpack menu will get stuck on the screen after exiting the menu. Re-entering and then leaving the menu will fix it.
We had something similar happening too but not just item description boxes. Ammo icons were getting stuck on screen along with other in game icons.
Just happened to me had to use the xbox magnifier to see that it was a shotgun ammo icon in the middle of the screen lol
It seems to happen if you look away before the card has fully rendered on screen - I’ve had it happen on XB1 as well. The quick work-around is to find something - anything - that has an item card and look at it. That displaces the ‘stuck’ one.
