Comment 15 for bug 1530180

I asked in #intel-gfx on freenode, the Intel graphics driver development channel and they suggested trying the i915g driver instead since it doesn't report an error in the same situation. They said the root problem is that "the shader is too long (instruction count) for the hardware" and that "the graphics hardware doesn't match the capablities that GL requires (and the driver is lying so that it mostly works.) There is a flag to disable the lie. But certainly try i915g, llvmpipe, or convince Qt to use a different back-end."
