Comment # 19 on bug 90264 from Furkan

I booted up a Haswell box from an Ubuntu 15.04 live USB, and was able to
reproduce the same glitch.

It looks like we can reproduce this on radeon, nouveau, and i965, but not
llvmpipe. What does that mean? I am re-classifying this under Mesa core for
now. Would it fit better under any other category?

Can anybody confirm that this issue isn't present with the Nvidia proprietary
driver?
