GMail screenshot

I started noticing this only a couple of days ago:

When I log in to GMail and try to use the Hangouts chat the display becomes garbled, and moving the cursor around only makes it worse. Menus stop appearing when you click on them and the UI becomes unusable.

I'm attaching a screenshot of the left bar.

The interesting thing is that this doesn't seem to be triggered by a WebKit update, and I actually reported <a class="bz_bug_link 
          bz_status_NEW "
   title="NEW - [GTK] Broken copy and paste in GMail Hangouts"
   href="show_bug.cgi?id=168769">bug 168769</a> using the same version of WebKitGTK+ (2.14.5).

I did however update many other packages on my system. I tried reverting the kernel, the X server and the video driver to the previous version but that didn't help. This problem seems to happens only with WebKitGTK+. Firefox or Chromium can open GMail just fine.

Another user reported to have a similar problem with WebKitGTK+ 2.15.90 and the hangouts.google.com website. I just tried that site with version 2.14.5 and it also breaks for me.

In case it's relevant I have an Intel HD Graphics video card (8086:0166).</pre>
