glxspheres64 is using 100% of the CPU. callgrind shows all of this is spent in:

100% intelBitmap
    |- 100% _swrast_Bitmap
        |- 50% intelSpanRenderStart
        |- 50% intelSpanRenderFinish

I'm a bit worried about "_swrast_Bitmap". Sounds like it's rendering in software for some reason. Although glxspheres64 says:

Polygons in scene: 62464
Visual ID of window: 0x99
Context is Direct
