Okay, based on the feedback it sounds like really this is more of a
performance concern. In normal operations on a system with decent
performance, the tearing is present but hardly noticeable, however on
systems with worse performance (or under a large amount of load) the
tearing can certainly be

lcampagn, how quickly were you moving the window at the time? I have to
move the window pretty fast to get the distortion as bad as in the
screenshot. I still notice it 'by eye' when moving windows normally, I
can easily ignore it in daily use; does it tear to the degree in your
screenshot during

Unfortunately the xorg.conf you've included contains a lot of overrides
for things xserver now autodetects, and it's possible some of your
overrides could be causing these problems. I would encourage you to
first reproduce this bug with a stock xorg.conf (i.e. move aside your
existing xorg.conf
I realized I may have just misunderstood the report - is the complaint
just that you don't like X's screen repainting algorithm? In that case,
you'd probably be best to take that directly upstream to the xorg-devel@
mailing list, since that's probably not something we would/could address
at the
My understanding of this is that it can't reasonably be done at an X
level, although X provides the ability for apps to sync-to-vblank.
As I understand it, the problem with getting X to do this is that it'd
have to check/sync for every drawing operation, making all drawing
substantially slower.
Hah! Listen to Bryce, he knows more than I do :). That's a pretty cool
screenshot, though.

The screenshot is pretty, but I think that's more of a gimp / screenshot issue
than the one I'm talking about :)
I've attached a photo of my screen while dragging a window. The exposure time
is about 6ms and shows the current frame, which is torn, and an older frame
which hasn't completely
I'm attaching the conf and log files from a Lenovo x60 tablet. The
graphics hardware on this machine is Intel Corporation Mobile

I'd be happy to attach files from several other machines if you think it
would be helpful..
