Hi Robert,
Could you have a look at osglogo to see how well it works with and without the PolygonOffset workaround.
With the Radeon workaround you only get the outline effect on the text closest to the the camera. With or without the workaround you get some flickering in the outline when the text is rotated. If I have to choose I prefer without the workaround. Regards, Brede On 7/15/06, Robert Osfield <[EMAIL PROTECTED]> wrote:

The OpenSceneGraph-Data hasn't changed, so the problem is likely down to ATI's driver.
