------- Comment #2 from [EMAIL PROTECTED] 2007-07-19 14:32 PST -------
The geometries are different because the vertex is shifted by a sub-pixel
length. As long as sub-pixel rendering is not used:
XXX
offset 0.0: XXX Vertex centre is on a pixel:
XXX 2n+1 pixels must be used to keep symmetry
XX
offset 0.5: XXXX Vertex centre is between two pixels:
XX 2n pixels must be used to keep symmetry
XXX
offset 1.0: XXX (Vertex centre is again on a pixel)
XXX
BTW, using fglrx (ATI X1300) I get a red dot, using ati (ATI X700) I get a dark
yellow dot...
