When holding maps or putting maps on item frames, they tend to glitch out by flashing for a moment, and then going blank for a couple seconds. This appears in the Crystal Palace RTX world.

What I expected to happen was that the item frames would hold a map just fine and blink.

What actually happened was that the maps blink repeatedly, and taking them out of the item frame and putting them back in, does not help. (The map doesn't even appear in your hands.)

How to find the bug:

1. Find the map room with 4 maps arranged on the table showcasing the entire world.
2. Try taking the map out and putting it back in the item frame.
