I also checked with my Tegra 3 device, and it has the same issue. But do note that this string seems completely garbage to me: Tegra 2/3 doesn't support full OpenGL, yet they return it in the client query. So I have doubts anyone is using this string for anything useful in the first place. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
