--- Comment #6 from Timothy Arceri t_arceri@yahoo.com.au --- Piglit test:
https://patchwork.freedesktop.org/patch/214341/
Mesa fix:
https://patchwork.freedesktop.org/patch/214346/
Note the WebGL test still froze in my testing but I think Firefox was continuing to use my system mesa libs for some reason. The mesa patch fixes the hang in the piglit test.
