Unfortunately, the test may fail on Linux with some drivers, e.g. Nvidia Linux driver implements the negative viewport quirk also in OpenGL.
It seems to fail here as well for me (Intel SKL, Mesa 17.3).
Right, it seems to be the same bug as Nvidia. I guess we haven't found earlier because Intel driver currently reports 0 for GL_VIEWPORT_SUBPIXEL_BITS.
FWIW, the test succeeds with radeonsi.
