I wrote a small game, using OpenGL, and I’m having a display bug on GeForce3.
It’s a really simple app (it’s a game, not a technical demo), it doesn’t use any extensions (only textured cubes
with some blending).
the game works fine on GeForce2, and on GeForce3 with antialiasing turned ON
(2x, quincux, or 4x)
but, when I turn OFF the antialising, some lines appear on the textured faces.

the game can be found here: http://oplayez.free.fr/mymahj34.exe
I tried with the drivers 30.82 and 40.71
Is it a driver bug ?
If not, how can I fix that ?
I submitted to DeveloperRelations@nvidia.com, but I have no reply yet.
I don’t own any GeForce3, so it’s hard to debug. Anybody experienced something like that. The fake bump mapping effect uses 3 passes. I wrote a 2 passes version (only 2 texture units on GeForce2) and I had the same display bug.
