No it's not the same at all: KUbuntu 9.04 x86_64 - kernel 2.6.28-11 SMP x86_64 g++ is 4.3.3 Nvidia drivers 180.51 OSG version 2.8.1 >It's a nightmare not being able to replicate it. You've really done a lot of work, and a good job, this nasty bug is probably a combination of factor... I wonder how numerous we are having this bug ? So far if we are only 2, you don't have to worry that much. If someone else using a Linux 32 bits distribution could test as well... I won't have many time next week, but if I can, I'll try to witch the 2 cards, just to see if it's working well with the 4600 on debian 32 bits... > > I starting to think it might be because I've used degenerate triangles in the > primitives. > >>When I reach the water surface, the >>view is flickering until I'm completely underwater...
