--- Comment #7 from Martin Lambers marlam@marlam.de --- I don't have access anymore to the AMD graphics card that originally exposed the problem for me.
I can only confirm that the problem does not exist with Mesa 9.0 (from Ubuntu 12.10) with an Intel Sandybridge GPU: OpenGL Version: 3.0 Mesa 9.0 OpenGL Renderer: Mesa DRI Intel(R) Sandybridge Mobile OpenGL Vendor: Intel Open Source Technology Center
Thanks for your work.
