Weird blue halo-like light effect

Has anyone else gotten this?  Have seen in a couple of movies.  Recently hooked up livewire powerline .  Never noticed before.  Video flawless otherwise.  Just a horizontal blue streak or ray of light coming off of artificial light sources in some scenes.  Very annoying and cannot possibly be native to the film.

Thanks

Answered is myself.  It is anamorphic lens flare.  I personally think it looks horrible.  Well, happy it isn’t a defect in my setup.

…which is native to the film.  ;)

Unfortunately :cry:  But thanks for the helpful comment.
