When running a Windows OSG 3.0.1 application under Windows Remote Desktop the OpenGL driver defaults to the (ancient) software MS OpenGL GDI renderer v1.1. Unfortunately, I need to make the basics of our app work under RDC.
I am finding that glDrawElements ( called from void DrawElementsUInt::draw) crashes every time inside the MS OpenGL driver when given a geometry with say, 3000 elements. With smaller numbers of elements there are no problems. This is code that works perfectly when running under accelerated drivers such as nVidia/ATI etc. I experimented with breaking up the drawing of elements into blocks of size GL_MAX_ELEMENTS_INDICES_WIN with no luck. It seems that repeated calls to glDrawElements in a loop even with a small number of elements cause the same issue. This is almost certainly a bug in the driver, but I am wondering if anyone has a workaround that can be done at the OSG level.
