OK, I have a curious data point.  I assumed the problem would be
somewhere in the drm update, so I started bisecting that at the top. 
 However, the top most commit:

commit 1d6da87a3241deb13d073c4125d19ed0e5a0c62c
Merge: 1f40c49 a39ed68
Author: Linus Torvalds <torvalds at linux-foundation.org>

    Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Isn't actually bad.  There's no flicker here, so whatever caused the
problem came from some update after this.
