When a gravity block is pushed fast with a piston and another block it makes them overlap and have weird collisions and the block (non-gravity) jumped when I tried to recreate issue in a test world. By jumped I mean it skipped a block and went up. The main issue is the weird gravity block interaction as in the picture/video Here is a link to the video I posted on Youtube of the bug https://youtu.be/LMw_4ZKZH7Y?si=SKui3nxTBUlPj3G5 or if the link is not useful My yt is Moboxic here is also a quick image of it

I am using the texture pack Clarity it is well know and does not have problems
