Description Luke 2016-07-24 20:03:53 UTC

With a GeForce GTX 650 and Mesa 11.2.0 I'm getting the following failure on Google Chrome and Firefox


https://www.khronos.org/registry/webgl/conformance-suites/1.0.3/conformance/glsl/misc/shaders-with-invariance.html?webglVersion=1


test: vertex shader with variant varying and fragment shader with invariant (global setting) varying must fail

FAIL [unexpected fragment shader compile status] (expected: true) vertex shader with variant varying and fragment shader with invariant (global setting) varying must fail

I believe this is a core mesa issue, not something nouveau-specific. I get a few failures in there (including the ones you point out) with i965/SKL and Mesa 12.0.1.

Comment 2 Luke 2016-07-25 03:08:37 UTC

Yes, I'm seeing these errors even with llvmpipe (LIBGL_ALWAYS_SOFTWARE=1 ./firefox).

Tests still failing on 13.0 with Arch

This test is passing on i965 with following versions:

Google Chrome 55.0.2883.87
Mesa 17.0.0-devel (git-0252ba2)

Works with recent radeonsi too. Closing.
