Mac OSX OpenGL problems

Hi,

My app, Panini, uses OpenGL to render views of panoramic images. It is pure Qt (4.2-4.5) apart from the OGL code. It works fine on Windows and Linux platforms but has display problems on Mac OS X, especially when rendering cubic texture maps. The problems take different forms on different Macs, and some Mac users don't see them at all.

I suspect this has to do with how Qt creates the OpenGL context, but maybe my OGL code is somehow at fault. Anyhow, I'm pretty Mac-illiterate, don't own one, and really need the help of a Mac graphics expert to sort this out. If any such are reading this, please help.

Panini is an open source project; you can get it at http://sourceforge.net/projects/pvqt/

Thanks, Tom
