Method 9: Remove DreamScene
I’ve thought I posted this already, but I haven’t. Anyways people have reported that disabling Dreamscene (playing video in the background) will fix the problem. To disable Dreamscene: Goto appearance and personalization in Control Panel. Select Personalization. Select Desktop Background. Select any thing other than Windows Dreamscene Content. Select a background and click Ok. That should disable Dreamscene.
