I wrote about it in bugs.freedesktop.org, you can see there: https://bugs.freedesktop.org/show_bug.cgi?id=55396
Yeah, I'm CC'd on that bug.
But regression test shows, that it's probably problem in Wine, not in Mesa drivers.
I'm not sure I really agree with that conclusion, but it doesn't really matter for fixing the bug. The most important thing to get at this point would be profiling information with proper call information. Unfortunately I don't have the required hardware to reproduce this myself. If you're unable to create a good profile yourself (or anyone else with the required hardware on this bug), your best bet may be to ask one of the Intel guys if they can reproduce it and create a profile.
