It didn't help.

It passes both times, i.e. I get:

PIGLIT: {"result": "pass" }

Although you didn't write it explicitly, I assumed that I had to build
piglit (and waffle) from source (current git master branch). I have
never compiled or used piglit before, so if my result doesn't make sense
or some information is missing, please tell me because I might have done
a mistake.

Thanks,
Viktor
