I've stumbled upon a really annoying performance issue on Intel GMA 45 on my Thinkpad T500. No response in the actual bug report (anymore) https://bugzilla.redhat.com/show_bug.cgi?id=977391 and no one on the IRC channel https://01.org/linuxgraphics/community/mesa . I'm willing to set up a meeting and spend even hours on the subject, as long as I got someone to talk to with the intent to tackle the issue.

Any thoughts?
