--- Comment #3 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Is also visible in Synmark's Batch* tests, so this can be trivially caught by
its validation.  Besides the vertical stripes, there's also noise visible in
some of the triangles, so there might be even couple of separate issues.

Happens only on HSW (GT3e), not on IVB or BYT.
