      RX580, Chrome 64.0.3282.186:
      • Windows 10 with the latest AMD drivers (18.2.3): 4/15 tests passed
      • Linux (kernel 4.15.6, Mesa 18.1.0-devel (git-b9636fe38a)): 5/15 tests passed
      Interestingly enough, 11/15 tests passed on my Nexus 6P running pretty much the same Chrome version (64.0.3282.137)

        Same here and I also get "0:650(1): error: syntax error, unexpected '}'" in some tests (Chrome).

          Did not crash but got only 3/15. Not a single image was actually rendered.

            R280X on 4.15 with amdgpu, mesa-git (0c983b9094) and llvm-svn(326330), 15 crashes the computer, the mouse still moves but that's it, 'restart' won't restart the computer I have to power it down manually.

            The @GraphicsFuzz demo found 4 issues (11/15 tests passed) on my desktop device, affecting my @AMD GPU driver.

              This seems to be as much browser as well as driver dependant ... f.e. I tried 2 firefox versions on windows and both give the same errors on the first few tests while one windows is on ryzen 2500u and the other has an intel core i5 mobile chip ...

                I find it funny that Mesa gets an article about a vulnerability, but *every other driver* fails 5 times harder on the same suite.

                    The website is down, I wanted to try this, as it could be a nice source for reproducible crashes of sandy bridge iGPUs, which are particularly nasty with linux, I've had crashes while messing around with plan webgl demos before.

                    Is there any mirror that actually works? Wayback machine doesn't load the demos (I assume it doesn't store AJAXed resources).
