When placing a map into an item frame the map is now affected by lighting properly but occasionally has a rendering error depending on how other maps are placed around it.

Steps to Reproduce:

1. Open any world with Ray Tracing on and in version 1.16.210+
2. Place multiple maps on a wall using item frames (preferably in a low-light environment as it is more noticeable)

Observed Results:

The framed maps constantly flickers depending on the player's viewing angle

Expected Results:

The map should remain as a stable image and not flicker.

You can download the PBR resource pack I used to take these screenshots and demonstrate the issue here:
