Cursor freezes for a split second around every 10 seconds My cursor on my Mac (running the latest version of El Capitan) has been freezing for a split second around every 10 seconds – it then reappears in the place it should've been if it hadn't disappeared.

I've tried using a different mouse – still occurs. And have done a PRAM reset.

Anyone have a clue of what could fix this?
I've had something like this issue (with the mouse freezing momentarily every few seconds), and it was related to my second screen. If I left this second screen turned off after waking the Mac from sleep (or from having the laptop lid closed), this issue happened every time

Also had an issue with it even when the screen was on; it usually cleared after I unplugged and replugged the second screen cable.
