Small black squares "jumping" over my Screen

[Wolfi_J]

I bought the notebook about 5 weeks ago. After about 2 weeks, some black squares appeared on the screen. Sometimes there are more, sometimes less.
Even a complete new installation did not work. It started showing these black squares again after a few weeks. They bounce across the screen.
When I record the screen with software, the squares are not visible on the video.
That's why I filmed the screen for you with my cell phone. [edit 
I hope someone can help me.  Michael

@ Wolfi_J Welcome to HP Community!

I understand that you are getting black squares on your screen.

As you state that this just started recently I would like you to review the HP Support document: Using Microsoft System Restore (Windows ), and follow the instructions within to restore your computer back to a point in time prior to the issue. I believe this is an update that was not successfully installed and the steps within this document will help you fix it.

Keep us posted,
