[Intel-gfx] [PATCH 5/5] drm/i915: Use atomic commits for legacy page_flips

[Matthew Auld]

I seem to be hitting some issues with this, at least in gnome-shell
which I bisected to this commit. Somewhat hard to describe but the
background window or desktop is partiality and intermittently drawn,
almost like a flicker onto the foreground window, title-bar etc.
typically during any kind of transition animation, like switching
windows, though sometimes just at random. Any ideas, I take it you
haven't seen anything like this while testing?
