Decal flicker when character is moving

Cant figure out what causes flicker during movement nor how to prevent it. Any help is welcome.
Decal is a component of ThirdPersonCharacter blueprint.

Issue (green decal at characters feet):

Material details:

Anti aliasing is causing this. It’s one of the downsides of TAA as implemented in UE.

There is an option in the material settings called “Responsive Anti Aliasing” or something like that. Try enabling that and see if it helps. You can also make the circle thicker. With higher framerates it should become less noticeable.
