Screenshot of tearing: http://i.imgur.com/J2YWn.jpg
Tearing is visible whenever a video plays. Doesn't matter whether it's
in a media player or Flash, Xv or GL. Using an external screen does not
help.
I'm getting video tearing on an Asus EEE PC 901 using compiz+unity.
I've tried xv, gl, gl2 as video outputs for mplayer which all result in
video tearing. There is no video tearing if I use xv:adaptor=1 (video
overlay) as video output.
I have sync to vblank set in ccsm/opengl.
Let me know what

@Marius, no, since I'm having trouble getting testing feedback from
folks, I have not made plans to fix it at this time.

Sorry for the delay.
Outputs like xv non-overlay and gl both do not achieve vsync. Only xv
overlay.

I can confirm this bug is still an issue on Intel (core i3) last updated
4/19/11. It works fine in Compiz, but tears in Metacity. Are there plans
to fix this or do we need to hack around for a proper xorg.conf?

@Eric, does fiddling with Xv settings as per comment #6 make the tearing
stop? If not, see my q's in comment #3.

Title:
Loss of vsync when using Metacity.
I noticed the same thing in Natty with Xv textured video on Intel
i945GM. The tearing seems to disappear when using Xv video overlay.
You can try this in mplayer with the following command:
$ mplayer -vo xv:adaptor=1 file
Or by setting XvPreferOverlay to true in xorg.conf, the intel man page
This probably isn't an Intel specific bug, because I'm on NVIDIA
graphics (proprietary drivers) and I'm having the same problem.
BTW, I've never been able to get vsyncing right with Compiz, but
Metacity has always worked perfectly for me (Maverick and before). With
Natty I can't get vsync to work
@Geert, well, vsync/tearing issues are such a generic symptom that two
drivers could have essentially the same problem with no common code
involved at all. In any case, these types of issues are best handled as
per-driver since even if there was shared code it'd probably require a
driver
Interesting. A few random troubleshooting ideas. Try moving aside your
.drirc. Run a video player with its --debug option and look through its
output for any noteworthy error messages. I notice a fb tiling warning
in your Xorg.0.log. Do a 'tail -f /var/log/Xorg.0.log' in a console
window and
