It's not impossible that there are two different regressions, one=20
causing sluggishness and one causing graphics corruption, or that they=20
are intertwined. I have a Kaby Lake system which I run these tests on.=20
I also have a window where the regression seem to have happened.=20
r333269 to r333340, so once I have time I'll start bisecting.

Hopefully I can test on older systems as well.
