err:d3d:wined3d_debug_callback 0x1bbac7d8: "glPointSize parameter <size> has an invalid value 'nan': must be greater than 0.000000 (GL_INVALID_VALUE)".
Those are essentially bug 22922 / bug 23048. Making them go away would require some tests to see what is supposed to happen when the applications sets NAN as point size.
Those messages have nothing to do with shader compilation though, which is what this bug claims to be about.
