black lines trailing 3d cursor

How do I get rid of these black lines trailing the cursor.

What black lines trailing the cursor? I don’t see a screenshot in your post.

The problem went away. Next time I will post a picture. The reason I did not was that I thought it ocured a lot and someone would know what the remedy was.Thanks
