Pause menu flashing

EDIT: I unplugged all of my USB devices, and this stopped happening, so I’m assuming one of them was to blame.

I’m seeing this issue where the menu is constantly opening and closing in the simulator.
It’s making all games unplayable for me.
Is anyone else seeing this?

Couldn’t attach the video, but here’s what it looks like: http://www.mediafire.com/file/gieus4abuy3zry0/file
