OS Version: OS X 10.11.4

When I saw this first I thought this issue is because I use OSX 10.11.4 at a virtual machine, but then another Tampermonkey user reported the same issue at OSX 10.10.3 (https://forum.tampermonkey.net/viewtopic.php?f=17&t=1705).

I've attached a video of the issue and the captured Chrome log.
The following line seems to show the root cause:
>2016-03-23 09:15:58.308 Google Chrome[1422:27319] HIToolbox: received notification of WindowServer event port death.

A quick search indicated that this is due to graphic driver problems.
