Hi Brian, all, Thanks for the follow-up, and congrats to the team for the prompt bug fix! We've just tweeted about it: https://twitter.com/GraphicsFuzz/status/968815766681333760
We'll be pleased to report further Mesa issues as we find them, yet as a three-people team we unfortunately do not have the human resources to do proper testing of Mesa on various platforms right now. Meanwhile, our public demo gives a nice excerpt of our test suite, and is easily ran via a web browser, so don't hesitate to try it on your devices: http://www.graphicsfuzz.com/#demo Please let us know if it triggers other issues in Mesa!
