When placing a painting, it checks for intersections with other paintings and most blocks, but does not check for intersections with glow item frames. As a result, they can overlap, which causes heavy z-fighting.
Normal item frames used to have the same issue:
Steps to Reproduce:
- Build a wall
- Place a glow item frame on the wall
- Place a painting to the left of it
The painting and glow item frame overlap.
The painting treats the glow item frame the same as another 1x1 painting, and will choose a size such that the occupied block is not overlapped.
