<pre>Not sure where to report this issue, as title says, problem is not present with
VBLANK enabled.
Vblank is disabled in both xorg configuration and .drirc profile (and clutter
when using GNOME).
Expected behaviour (DRI2):
When scrolling pages (with smooth scroll) in Chromium for example, it defaults
at FPS=refresh rate (my case 85Hz), there is just tearline present, everything
else is smooth and fine (as with vblank enabled, except tearline).
On DRI3 however, even on simple forums/text based pages, there is
stuttering/choppy scrolling.
GPU is HD 6770, Xorg server version is 1.19.1, if you need more
information/testing, would be happy to do it.</pre>
