Guessing from your description that this is an OpenGL program ? Linux or Windows ? If Linux, does it run on the Intel driver ?
As a general rule if you're only going to develop on one platform you're better off using Intel or AMD, since both of those drivers tend to be equally strict about following the OpenGL spec. If you develop on NVidia hardware only the drivers will accept a variety of invalid sequences/values and silently correct them in an undocumented & vendor-specific manner, leaving you with code that only works on NVidia hardware.
Is there any other information when the bug occurs that might help ?
