    Phoronix: GraphicsFuzz Demo Works On Fuzzing Your GPU Drivers Through WebGL In The Browser

    In the past we have reported on work done by students at the Imperial College London on fuzzing OpenGL drivers and in the process uncovering various driver bugs affecting Linux too. They have out a new WebGL demo that has already uncovered at least one Mesa driver bug...

    Consider sharing your result on twitter, looks like linux + nvidia + proprietary driver produces 6 errors, 9/15 passed

      The @GraphicsFuzz demo found 9 issues (6/15 tests passed) on my desktop device, affecting my @AMD GPU driver, LOL (r600 Mesa), in Chromium probably because of extensions it's even worse 5/15 tests passed, than 4/15, this is very random...
      Chrome is trowing "0:650(1): error: syntax error, unexpected '}'" at shader compilation, while firefox does not.

        I tried it on my Win7+NVidia PC at work. With an updated driver 6 failed with linker errors, 1 failed to produce a picture and 9 were successful. Before updating (it was on 344), one of the tests actually crashed the driver. I'll have to check back home in Linux whether the results are similar.

          Test 15 hangs my os. I can only reset my computer.

          AMD rx 480
          Mesa: 17.3.5
          Kernel: 4.15.5

            The @GraphicsFuzz demo found 7 issues (8/15 tests passed) on my desktop device, affecting my @nvidia GPU driver and/or google ANGLE

            Its a bit disappointing that there are no results from the nativ OpenGL ES Implementations from the Desktop GPUs.

            EDIT: If i disable Angle, all Tets fail.

                Current nvidia windows 10 driver fails miserably, 8/15 passed.

                  AMD radeon driver on Kaveri fails only test 15, but that causes a complete system hang and the only option is a forced reboot.

                  kernel 4.15.6
                  mesa 17.3.6

                    Now making its way to an exploit kit near you!
