TAA issue with dithering (masked materials) in UE5

Hi!
First time writting here, I’ve been reading this forum dialy for years and it has helped me a lot to improve as VFX artist, but never comented due being log out XD

So I was doing a certain VFX (in which I can’t elaborate too much in the details due job reasons) and I’ve been stuck for some hours with a wall, basically for this effect I need it to be masked, so I am using a DitherTemporalAA with my mask as Alpha threshoold to handle the Opacity Mask.

The issue? We work with Temporal Anti-Aliasing as our rendering method and it produces a ghosting effect with the dither pattern. If I change the render method to FXAA (like you can see in the video that is a recreation with a Shader made just to showcase this issue) this issue is solved, but I can’t change the aliasing method of an entire project just for one effect… so I’m wondering if there’s any way to solve this issue or it’s just a live with it situation.
