--- Comment #2 from Stefan Dösinger stefan@codeweavers.com --- Changing GL_VIEWPORT_SUBPIXEL_BITS in llvmpipe is easy and it fixes those new test failures, but it introduces new ones. Apparently GL_ARB_clip_control has its own issues in llvmpipe. GL_VIEWPORT_SUBPIXEL_BITS=8 makes wined3d use ARB_clip_control, breaking some other tests in d3d11 and d2d1 (and maybe even more, I didn't test other modules yet).
