Windows8 Dell USB 3.0 Dock freezes mouse, monitor, ethernet

[rtozer]

I recently bought a Dell XPS 13 with a Targus dual display dock (through dell, but not branded).
I was experiencing the freeze issue described here, though mine never came back by itself once frozen. Screens, sound, ethernet, USB devices all frozen. Unplugging and replugging the usb cable usually reset it.
It always happened when opening a new tab in chrome and occurred a few times a day.
It was particularly likely to happen if I mouse wheel clicked a link to open in a new tab on the laptop display and then moved the tab to a displaylink display before rendering had completed.

I disabled GPU compositing and threaded compositing in chrome://flags and the problem hasn't occurred since. I've since reenabled threaded compositing and still no freeze.

Perhaps this will help others with the problem, and/or the developers.

Further info:
Running Win 7 Pro
I plugged in the dock without installing drivers, it attempted to install drivers itself which failed.
I then used the disc which came with the dock, which completed with warnings but after a restart all device manager warnings cleared.
I downloaded the latest firmware and displaylink drivers, both said I already had the latest installed.

All was working fine till yesterday when I installed the latest Intel HD 4000 drivers.
I still don't have the freeze issue, but now rendering gets badly messed up if I scroll a page (in any app), and overlays flicker badly and/or disappear (image alt text etc). Turning GPU compositing back on didn't resolve this.
The scroll issue makes the displays completely unusable.

edit:
Update - having windows install the HD 4000 drivers seems to have resolved the issue, right click - update driver software in device manager, as opposed to downloading and installing from Intel's site. Same driver version, but all scroll and overlay flickering is gone.
