Created attachment 140321 [details] glxinfo https://www.khronos.org/registry/webgl/sdk/tests/webgl-conformance-tests.html Using the WebGL 1.0.4 conformance test on my Sandybridge laptop. conformance/glsl/misc/fragcolor-fragdata-invariant.html (Passed: 1/2 Failed: 1/2 in 582.0 ms) failed: [unexpected fragment shader compile status] (expected: true) Declaring both gl_FragColor and gl_FragData invariant should succeed. The other subtests are OK. I'm using Mesa 1.8.1.1 on Firefox 60.0.2 Manjaro Linux (i've attached a complete glxinfo).
I've retested 2 times the WebGL CTS 1.0.4 with Mesa 18.2.6 and Firefox 64.0 on Manjaro Linux up to date and now the test pass correctly ---------------------------------------- conformance/glsl/misc/fragcolor-fragdata-invariant.html (Passed: 2/2 in 788.0 ms) Declaring both gl_FragColor and gl_FragData invariant should succeed. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". test: Declaring both gl_FragColor and gl_FragData invariant should succeed. default vertex shader default vertex shader translated for driver test fragment shader test fragment shader translated for driver PASS Declaring both gl_FragColor and gl_FragData invariant should succeed.
