Random Artifacts in view port

Yes, I have asked this before, but how my other post is too old I prefer to
Re-ask it. So I followed a lightsaber by @Ian Hubert on his youtube channel.
so how blender 2.9 is released I wanted to try the New motion blur.

BTW i using eevee. Any help is appreciated! :grinning:
