We are developing OpenGL window application and getting a strange bug when there are two displays in system with NVidia videocard.
When I drag-and-drop a window to the second display, part of the window that is placed on second display is not refreshed (Windows XP SP2/GeForce 8800GT) or rendertarget-textures are black (Windows XP SP2/GeForce 8600GT). We are using FBO for offscreen-rendering and detaching texture from FBO after every rendering to FBO.
Popular OpenGL applications, such as Tropics Demo (in OpenGL mode), work exactly the same in window mode on these configurations.
With ATI videocards on 2-displays systems everything is ok.
We suggest that this is NVidia driver bug. Driver version is 181.20.
We would appreacate a lot if anyone knows workaround for this bug.
