As of bug 19635, video tearing has been fixed but only in a non-
composited environment. As using compositing is very usual, this is
quite a big problem.

he doesn't push them out now."

Updated the summary and changed to an RFE. Last patch set went to dri-
devel under the subject "Another page flipping update".
Basically, compositing managers need a way of making sure their front
buffer rendering can occur w/o tearing. This includes composited video.
This RFE covers an tear-free glXSwapBuffers implementation that any
OpenGL application can use for this purpose. It's possible to do this
in other ways, for example through an X extension or something, but
that's a subject for another RFE if someone wants to take it on.

Maybe it is stupid but why not enable vsync for the whole composite
output? I mean who needs more than 60 fps anywhere? For benchmark
reasons there could be an option which disables it which results in
video tearing.

I think a lot of compositing managers will choose that option (when they
have updated frames to display of course). Right now though there's no
good way for them to sync all output. They can block on a given pipe's
vblank event, but that's racy, since the compositor process may not be
woken up in time or may not finish its drawing in time to draw w/o
tearing. So we really need glXSwapBuffers to be sync'd automatically,
which allows the compositor (or other GL apps) to prepare a whole frame,
swap buffers, and then continue rendering the next frame and not worry
about tearing at all.

Are there any patches to test or a plan for integration. Is it likely
that it make it into stable until October?
If so the next release will be really great for Composite.

This commit caused screen to stop redrawing. I use two monitors, laptop
screen and external one. Works ok if I disconnect external monitor but
it it's connected screen freezes.

Did you pull the updates after this commit? Eric fixed a few issues
with this patch in a later commit...
If things are still broken with master, please open a new bug.

I've found out what causes the problem. As I said before I have 2 monitors and I use them in extended desktop configuration:
xrandr --output VGA --right-of LVDS --auto.
The problem is that my LVDS is 1680x1050 and VGA is 1920x1200. So what I
get after xrandr is virtual screen 3600x1200.

if I instead did:
xrandr --output VGA --right-of LVDS --mode 1680x1050

everything works fine.
So I believe the problem is when driver has to redraw area that is bigger then physical screen. Maybe then there is no MI_WAIT_FOR_PIPEB_SCAN_LINE_WINDOW for
region which includes XXXXXXXX part (is partially below the screen).

This is still an issue with -intel 2.8 and i915. It is much better than before but still tears often during tracking shots.
So atm I have to disable KMS to use Overlay again.

Try using Option "SwapbuffersWait" "true" in xorg.conf

The option "SwapbuffersWait" prevents the tearing of long lines but there are still from time to time fractals like short rectangles slower than the rest which makes watching a movie still kind of annoying some times.
The main problem is that it isn't possible to use Overlay again with KMS.
