I searched but couldn't find a dedicated thread for this bug.

Sometimes (not often) a shelve of random items that includes a mixture of food, books, useless junk, etc., will become completely invisible. The items are briefly visible for a moment before they vanish completely without any interaction on my part, only some camera movement; however, they are still there because I get the hover message when the mouse is pointing at an item's location and can still interact with every item as if they were visible.

After interacting with any one of the items, the entire shelf becomes visible again.

This glitch usually only affects a single row on a shelf, but I've also seen it happen to a group of Dwemer junk items sitting on a floor. The latter was a strange cicrumstance though because usually I see the items briefly before they disappear, but in that case I walked right by them and they definitely weren't visible, but then on my way back I noticed a message flash quickly indicating that something was invisible on the floor. Sure enough, holding E to grab the item made the whole set of items visible.

It would be nice to see this fixed in the next patch, but it's not a priority for me. There are plenty of game-breaking keyboard, mouse and quest bugs that really need to be fixed first.
