Created attachment 122788 [details] apitrace I've been running these examples: https://github.com/McNopper/OpenGL There don't seem to be build instructions... This works for me: cd GLUS cmake . make cd .. cd Example40 gcc src/*.c -I ../GLUS/src/ -lGLEW -lGL -lm -L ../GLUS/ -l:libGLUS.a -lglfw MESA_GL_VERSION_OVERRIDE=4.3 MESA_GLSL_VERSION_OVERRIDE=430 ./a.out Intel renders this brokenness: https://www.youtube.com/watch?v=BCIh5MTDRNo radeonsi renders this, probably correctly: https://www.youtube.com/watch?v=Xlz36lyMFcg Both videos are actually created with mesa git from the same attached apitrace on this hardware: 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M] (rev ff) There are no shader compile errors and mesa and apitrace report no GL errors I can see so I assume intel should be able to render it correctly.
Jordan, can you take a look?
Works now. Possibly because of the recent changes like https://cgit.freedesktop.org/mesa/mesa/commit/?id=357495b94dad4101a5491ed30782574162de58db (but I didn't test it)
