When I am in play mode, and I get close to the effect I get this artifacts, they don’t show in edit mode when I am placing things in level. If someone has any idea what they are and how to remove them. Thanks for your answer, contribution in any case.

When I am playing the game. [artifacts present]

When I am editing the level ( no artifacts )

Another Example
( No artifacts )

( With Unwanted artifacts )

I have found partial Solution of
solving the artifact problem ( Go To Project Settings>Rendering> (and Disable Motion Blur)

I have found another solution in which you don’t have do disable motion blur globaly.
You can just change the settings of rendering inside emitter.
