Follow up from ticket:1358#comment:5, enhance the GL check code to create a temporary window with textures and go through one fake paint call to verify that the opengl driver is usable.
Done in r15007:
Warning: vendor 'NVIDIA Corporation' is greylisted, you may want to turn off OpenGL if you encounter bugs
OpenGL test rendering failed: OpenGL RGBX paint error: GLError( err = 1281, description = 'invalid value', baseOperation = glClear, cArguments = (116384,) )
And opengl should be disabled on those broken chipsets.
Intel driver woes continue: ticket:1469#comment:14.
Works as well as can be expected, next step will be opengl in python3: #1569
