[Launchpad Bug Tracker <214154@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

The VSYNC (aka VBLANK, aka wait for retrace, etc) works badly with and
without propriety (fglrx) driver. This considers 2D and 3D graphics.

When enabled in "amdcccle" (can be enabled for 3D only) - some 3D
windows flickers partially or fully with black color (background), all
animations are rough - jumping periodically, or, on bigger windows, one
can see clearly a line in one position, on which animations (like video
playback) are being "cut". There is sometimes another "cutting line"
visible - only that this one is not horizontal, but diagonal. glxgears
reports more than real monitor refresh rate (should be 60Hz - LCD
panel), unless all of "amdcccle's" settings are set to max quality
(Anisotropic filtering and Anti-aliasing).

There is also a problem with compiz described in bug #212587.

Another thing - before starting compiz: 
  $ glxinfo | grep direct
  direct rendering: Yes
and SOMETIMES on compiz running, and after turning compiz off it reports "No".

# aticonfig --vs on
Sets xorg.org without error, but still, it has no effect after X restarts.

Please look at bug #213554 also.
