Comment 13 for bug 242990

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 seen. I suspect we're going to just have to accept it as the way it works when in degraded circumstances, and focus on addressing the underlying performance issue, rather than fiddle with the drawing algorithm to hide the bad performance. As raof mentions, changing that algorithm probably would cause worse behavior in some other situation.

lcampagn, so I think you're right this can be closed, and instead focus on the compiz performance problem. Have you opened a bug about the sync problem against compiz? If not, please go ahead and do so.

In the mean time, if you do bring this issue up on the Xorg upstream mailing list, and get any further info that we may want to look at for ubuntu, please feel free to reopen this bug.
