Jitter in translucency material

Hey guys!

I recently started studying Unreal.

I’m stuck with some king of bug, there is a quite simple glass material, and I like how it works, but when it play in sequencer or render via render queue, there is a jump or jitter in the transparency, it looks like a bug, because the sphere and the cone are the same material, and there everything is fine, but when I apply the material to the cube or plane, there is this jitter.

I have already switched all possible ticks in the material and the post process volume, but nothing helped.

I will be grateful for your help.

PS Here is screens for material and ppv
