Comment # 4 on bug 82253 from Michel Dänzer

Could be an issue in st/mesa or other driver-independent Gallium code then.

Does glretrace also report a few OpenGL API errors like these on intel?

5946: message: major api error 1: GL_INVALID_OPERATION in Inside glBegin/glEnd
5947 @0 glTranslatef(x = 2.000085, y = 0, z = 0)
5947: warning: glGetError(glTranslatef) = GL_INVALID_OPERATION
