intel driver: pymol ray tracing demo screenshot

Filed from caserun https://tcms.engineering.redhat.com/run/273669

Version-Release number of selected component (if applicable):
RHEL-6.8-20160215.n.0
xorg-x11-drv-intel-2.99.917-0.2.20151111.el6.x86_64

Setup: 
 1. Ensure the 'nomodeset' kernel parameter is not set in your bootloader
    configuration
 2. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that
    uses the valid driver
 3. Ensure that glxinfo | grep 'OpenGL renderer' does not return OpenGL
    renderer string: Software Rasterizer
 4. Install the pymol package with the command yum install pymol
 5. Launch pymol from a terminal

Note: You may need to install some additional packages serach https://
brewweb.devel.redhat.com and http://koji.fedoraproject.org (there is a lot of
packages also for RHEL6).

Steps to Reproduce: 
 1. Go to Wizard => Demo => Representations. There should be a list of demos on
    the right side of the Pymol viewer window
 2. Click on Ray Tracing demo. Interact:
     1. Use the mouse wheel to increase or decrease complexity
     2. left-click+mouse to rotate
     3. middle-click+mouse to move around
     4. and right-click+mouse to zoom in/out

Actual results: 
In most positions of rotation there aren't reflections on molecules.

Expected results:
In second attachment is screenshot from same demo, but with different graphics card using ati driver. There are reflections on molecules in every position of rotation.

Graphics card:
Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16]

See reflections on molecules, which aren't on first screenshot.
