The Bug
I loaded a world and searched for a village and i found bells following the camera, in pillager outpost banners were also weird, i didn't screenshot it when I found, but i could replicate it in a superflat world. I made a superflat and placed the blocks to replicate it
Affected Items:
Shield
Affected Blocks:
Bells
Banners
Piston
Door
I think this bug is a problem with block with animations ( moving banner, bell ring and piston push ) and 3d items ( shield and resource packs )
