Screengrab shows a (trapped) chest lid open in front of a map in an item frame. (I don't think the fact that it's a trapped chest matters for this issue.) Note that the latch of the chest is visible (roughly in the middle of the map), but the rest of the lid does not appear to be shown at all.
I don't think this is Z-fighting as there's no flickering, and the lid remains invisible as long as the chest is open, but nevertheless MC-2195 describes a similar problem. However in my bug I can't see the lid at all, whereas in 2195 the chest lid and the item frame are both visible.

I read that report, and I don't think it is a dupe. Differences are: I'm in the /chest inventory screen/, and for me the chest lid is /invisible/ (apart from the latch). In MC-1759 the chest lid is visible but clashing with the item frame.
Updated summary and description of MC-1759.
