Open GL slow / unreliable when screen rotated
Hi There,

I'm experiencing a problem with the ION board when trying to run my OpenGL application on a display that's rotated 180 degrees.

It no longer renders reliably, seems very slow and some items don't draw at all... rotate back again and all works fine...

Any clues as to the cause and a possible fix would be much appreciated.

Motherboard is Asus AT5IONT-I running Windows XP embedded SP3.

Please ping me if you need specific info on my setup and code etc.
