I was hoping for a (what appears to be a "not our bug") response that was more helpful WRT whose bug it likely is. To me it's clearly a bug report that either can be found or needs to be made at bugs.freedesktop.org, but in what component? https://bugs.freedesktop.org/describecomponents.cgi?product=xorg has a long list, among which there is only one that includes the string intel, Driver/intel, which is what this list seems to be about. Does it look like Server/General, Server/DDX/Xorg, or something else? As it manifest in more than one distro, it surely isn't likely to be downstream.
Userspace modesetting is known to be racy and broken, so people don't really want to waste time on digging into bugs which are most likely flukes. But if you can bisect this issue to a specific patch a fix should be possible.
Again I got no clear answer to the question asked, so I guess now it's fair to assume this must be the right place for discussion after all.
I've installed openSUSE 12.3. Its 3.7.10-1.16-default and server 1.13.2 behave nicely. Beyond installing Mageia 3 to get 3.8.13 and 1.13.4, and as one who does not build software even via proxy, I'm open to suggestions how to get kernels and/or other xorg versions needed to perform bisection.
