GLSL Version Number detected: 1.2 This is not enough: we need GLSL1.30 or later. You should update graphics drivers, graphics hardware, or use the --mesa-mode option. Else, please try to use an older version like 0.12.5, and try there with --safe-mode You can try to run in an unsupported degraded mode by ignoring the warning and continuing. But more than likely problems will persist. Segmentation fault
