Bloom flickering when moving?

I was just struggling with the exact same problem, but I think I found a solution. My guess on how this works is that the bloom works by what the camera is displaying, but some pixels are distorted when a camera moves, meaning that sometimes pixels are thicker and will cause more bloom than at other times. I had hoped that a pixel perfect camera would help, but it didn't do much. But in the FX pipeline asset if you enable anti aliasing in the quality settings and set the render scale below that to 2 (which may be resource intensive, I really don't know) that either removes the problem or makes it much less noticeable. Idk if this is actually helpful but I couldn't find anything anywhere that fixed it either, so I wanted to leave this here in case anyone finds it.
