MORE INFORMATION

OpenGL applications calling ChoosePixelFormat may encounter Access Violations (AV) during debugging. After calling ChoosePixelFormat, the debug window will display one or more AVs in Gdi32.dll. The number of AVs correlates to the number of pixel formats for the device being used. This is a benign behavior that appears only with some video drivers.
