In a large cityscape of loaded .osg/ive high-rise textured building models (LOD, not PagedLOD), initially everything looks great flying in and out around all the buildings, then sometimes after a while some of the building texture faces turn white. I know that invalid/incomplete GL textures will be rendered white, but initially all the textures looked perfect.
If the textures got paged out by the graphics pipe, I would expect to see a slight rendering delay when they get paged back in, but not turn white. But even more confusing is that on a single CPU WinXP laptop (2yrs old) with Nvidia(256MB videomem) it runs fine - no white textures; but on a brand new WinXP quad-cpu (not threaded - so we're only using 1 of them) with the latest Nvidia(768MB videomem) the white textures problem seems to be getting worse (more frequent) over time! Could the inconsistancy across various platforms be pointing to a GL driver issue (i.e. different versions), or is there something is OSG that I can be looking at to fix this, or at least isolate what the problem could be?
