At least two function calls give nonsensical errors (the second of which actually prevents the use of VBOs at all). I've only confirmed this on Intel. See the attached test cases (both of which should *pass* on the buggy setup). Note that forcing a 3.0 context with -Djogl.debug.GLContext.NoProfileAliasing results in a working 3.0 context that won't give the errors detected in the unit tests. 2059 1 403 org.jogamp 2012-12-28 21:03:40 +0100 Created attachment 403 The second test as native code with GLFW 2060 2 404 org.jogamp 2012-12-28 21:04:20 +0100 Created attachment 404 The first test as native code with GLFW 2061 3 org.jogamp 2012-12-28 21:06:20 +0100 The native tests give the following output on buggy contexts: renderer : Mesa DRI Intel(R) Sandybridge Mobile version : 3.1 Mesa 9.0.1 vendor : Intel Open Source Technology Center glVertexAttribPointer: 502 renderer : Mesa DRI Intel(R) Sandybridge Mobile version : 3.1 Mesa 9.0.1 vendor : Intel Open Source Technology Center test-poly: glPolygonMode: 1280 2062 4 org.jogamp 2012-12-29 13:52:22 +0100 I've just discovered that glPolygonMode(GL_FRONT, ...); and glPolygonMode(GL_BACK, ...); are invalid under 3.1 - only GL_FRONT_AND_BACK is allowed.
