Stereo and Menus
I am developing an app that displays a stereo image using OpenGL Quad Buffering. I'm using a Quadro 3700 card with the 191.00 drivers (although this problem has also been confirmed on a Quadro 4500). This problem exists both with nVidia's GeForce 3D glasses/Samsung LCD monitor, and with third party glasses using a projection setup.

Stereo works fine until I open a menu (either a submenu from the menu bar at the top of the window, or a context menu) that overlaps the GL window. When the menu is open, the image is still being drawn behind it in stereo. Once I make a selection from the menu and it goes away, stereo "turns off" and only the left buffer is drawn to the screen. It stays like this until a repaint is triggered, then both buffers begin to draw again. This occurs in windowed or fullscreen mode. I don't receive any GL errors at any point.

Has anyone seen this before? Or is there a better place for developers to post? I tried to look for a place to submit bugs to nVidia, but all I could find was a bug submission form for GeForce cards.

Thanks for any help!
