Unhappy Slow glPixelZoom???

I don't remember glPixelZoom being slow in 3123, but in the new driver, it can take half a second (!!!!) to do a glCopyPixels(0,0,720,486) when glPixelZoom(1,-1) has been called.

i.e.
glPixelZoom(1,-1);
glRasterPos2i(0,486);
glCopyPixels(0,0,720,486);

takes half a second.

There is no good reason for this, glPixelZoom(1,-1) should be optimized, and I believe that it -was- before.

You know of any way around this? It is quite annoying to have to see video and our graphics upside down.
