Understood. I wonder if you have Nvidia GeForce Experience installed. I have read elsewhere that some of its overlay is source of the issue.

That said, if I had to venture a guess, it is not liking Fences. What I would suggest is turning of any 'overlay' that Nvidia is producing.
Also, any actively running Nvidia software is largely unnecessary. Other than its '3D Vision' product, it's uses are for reminding of updates and perhaps some video capture / gaming components.
