Thanks for narrowing this down Andriy.

You can confirm that this is a driver bug (not an app bug) by retracing the
working & broken trace files on other drivers/hardware:

 - Intel Windows OpenGL
 - AMD Radeon
 - Nvidia 

If they render better than i965 Mesa, then it is probably a driver bug.

Secondly, you can find the problematic shader using FrameRetrace:


For a short demo of how to find the shader for the bad render, watch this video
starting around the 10min mark:
