Can't reproduce this locally; currently on f22c055e4bd497ee3cde9a220e662c4df2cae5ff

dtseng@: could you take a look.

The swiftshader roll pointed to in this cl only contains 2 cls:
1) A TSAN fix which should be noop for anything but TSAN
2) A uniform block fix. Does this test use uniform blocks?
CCing capn in case there's some issue with the uniform block fix.

Note:
There's also been another roll since then:

Doubtful this flakiness is caused by our minor SwiftShader (OpenGL 3D graphics) change. The logs contain some warnings about user profile and network issues.
