You might expect that with "Sync To VBlank" enabled in compiz that video tearing doesn't happen. But it does, just less often.
This is normal, expected behaviour. The cause is that compiz (up to 0.9.6 at least) uses GLX_SGI_video_sync, which provides a rough way of synchronizing with the video frame rate of the monitor. But it's not reliable in most cases because if you take a little too long to render the frame, then you can miss the frame deadline and tearing can still be seen.
The solution to this bug is to modify compiz to use GLX_SGI_swap_control instead, which provides a more reliable and more efficient way of synchronizing with the refresh rate.
Speaking with smspillaz, he says a move to glXSwapBuffers is planned for a future version of compiz, not least because it is required in order to port compiz to OpenGLES. Once compiz uses glXSwapBuffers for every frame, it will be possible to then use GLX_SGI_swap_control for reliable synchronization.

description |
You might expect that with "Sync To VBlank" enabled in compiz that video tearing doesn't happen. But it does, just less often.
This is normal, expected behaviour. The cause is that compiz (up to 0.9.6 at least) uses GLX_SGI_video_sync, which provides a rough way of synchronizing with the video frame rate of the monitor. But it's not reliable in most cases because if you take a little too long to render the frame, then you can miss the frame deadline and tearing can still be seen.
The solution to this bug is to modify compiz to use glXSwapBuffers for every frame. And possibly, optionally, use GLX_SGI_swap_control for synchronization, though it might not be necessary when using pure buffer swapping.
Speaking with smspillaz, he says a move to 100% glXSwapBuffers is planned for a future version of compiz, not least because it is required in order to port compiz to OpenGLES.
More info: http://www.opengl.org/wiki/Swap_Interval
WORKAROUND:
In CCSM, Workarounds, enable "Force full screen redraw (buffer swap) on repaint".

You might expect that with "Sync To VBlank" enabled in compiz that video tearing doesn't happen. But it does, just less often.
This appears to be a regression in Ubuntu 11.10, because in 11.04 "Sync to VBlank" was working reliably and eliminated tearing.
Strangely, disabling just the Unity plugin in CCSM solves the problem and all tearing goes away. This seems to be related to bug 861061 where the Unity plugin also degrades application frame rates. Both issues are instantly solved by disabling just the Unity plugin.
WORKAROUND:
In CCSM, Workarounds, enable "Force full screen redraw (buffer swap) on repaint". With some graphics drivers like the NVIDIA proprietary one, this workaround may introduce stuttering and halve the framerate you see. That is expected with some drivers and is fixed by the same compiz fix that is proposed for this bug.
If you are using the "nouveau" driver for NVIDIA chips, you will need to enable Sync To VBlank support in the driver options because nouveau has it disabled by default. You can do this be editing /etc/X11/xorg.conf and adding:
# For nouveau only:
Section "Device"
Identifier "My Graphics"
Option "GLXVBlank" "on"
EndSection
Then log out and in again for it to take effect.

If you are using the "nouveau" driver for NVIDIA chips, you will need to enable Sync To VBlank support in the driver options because nouveau has it disabled by default. You can do this by editing /etc/X11/xorg.conf and adding:

USERS OF THE CATALYST (FGLRX) DRIVER:
The fglrx driver also disables Sync to VBlank support by default. To fix this:
1. Open Catalyst Control Center.
2. Go to 3D > More Settings.
3. Set "Wait for vertical refresh" to "On, unless application specifies".
