Win7 Release (NVIDIA) bots failing reliably:
https://ci.chromium.org/buildbot/chromium.gpu.fyi/Win7%20Release%20%28NVIDIA%29/
since:
https://ci.chromium.org/buildbot/chromium.gpu.fyi/Win7%20Release%20%28NVIDIA%29/32112

with what may be a driver crash.

The test failure is:
WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_sub_rectangle_tex_2d_rg16f_rg_half_float
although there was one flake of:
WebglConformance_conformance2_textures_canvas_sub_rectangle_tex_2d_r8_red_unsigned_byte

The regression range is:

Suspecting:
http://crrev.com/c/765060 Disable scissor rectangle during implicit clears in RGB emulation path.
or the WebGL roll:
https://chromium.googlesource.com/external/khronosgroup/webgl.git/+log/34842fa..12192b9
but not sure which. The WebGL roll did not change the test which now fails.
