When I switch between windows or tabs (Chrome, PHPStorm), the rendering of the page doesn't complete. It looks like the screenshot below and only changes when I resize the window or scroll down.
Playing video's is not a problem, so it's not just about slow rendering.
I've got no clue how to debug this problem. How can I find out what's the actual problem?

I found this bug report. It looks like there is a feature called virtual contexts that is causing problems with Intel MESA drivers.
This is the code review for the respective regression.
UPDATE (10/16/2015):
This fix is available in Chrome Dev (48.0.2535).
