This issue is caused by missing ARB_geometry_shader4 in AMD driver. Is it possible to enable ARB_geometry_shader4 for OpenGL 3.1 driver? Or this function needs OpenGL 3.2? Thanks.

Comment 4 Hai 2019-01-09 06:32:46 UTC

Since ARB_geometry_shader4 is from OpenGL 3.2, this issue is a test case bug rather than mesa bug. Will close it.

Note that ARB_geometry_shader4 is actually a separate extension, with functionality that's slightly different than what's included in GL 3.2 core. Mesa has no current plans to implement that extension.
