        Can you drill down on this a bit? Which subtests get most worse?
        

      I have compiled the results into a spreadsheet. There is not one
      sub-test that performs worse than another. The overall times are
      slower with modesetting.

    TL;DR:

    DrawingArea Circles seems to be the worst offender: it runs at 40%
    of Intel speed and is used relatively often in this test; other
    significant slowdowns are around 83% in ComboBox*

    The worst offender is DrawingArea Pixbuf running at 25% of Intel,
    but not very significant in this test because it runs for very short
    time.
