Jan, all the builds you mentioned are bad on my machine. Using: Intel Open Source Technology Center -- Mesa DRI Intel(R) Sandybridge Mobile

Oh :( Maybe your bug has a different regression window than the others.

Unfortunately, this issue has gotten annoying enough for me to disable WR (I'd really like to keep it enabled) for now. If you guys can't locate a machine, I suppose I could send my machine to you if Mozilla would pay for shipping from NY (sadly, I'd want it back as well). Please let me know if there's any other way in which I can help, and obviously feel free to clear the NI request if you'd rather locate a machine locally.

Milan, do we have any machines with Sandybridge GPUs in Toronto office that we could try to reproduce this with?

Milan is on PTO. Jeff, do we have any machines with Sandybridge GPUs in Toronto office that we could try to reproduce this with?

Yep. I can try to reproduce it. Here's a list of the machines that we have: https://wiki.mozilla.org/QA/Platform/Graphics/Inventory

I can reproduce this.

Asif, what version of mesa are you running? i.e. can you attach the contents of glxinfo?

We figured this out. kvark will create a PR.
