RE: [PyMOL] lines same color as background
Zac, Thanks for the report. The fact that it happens with Ono too indicates that it is a driver/openGL-level bug. You can try some things like disabling depth cuing (set depth_cue=0) or smoothing (set line_smooth=0), but most likely you will need to wait for a driver upgrade. Please do report the problem to nVidia tech support and clearly state that the problem occurs across multiple OpenGL programs. Also, you might try using an older version of the driver. AFAICR, nVidia uses a unified driver architecture which is both backwards and forwards compatible. If you do find a robust solution, please pass it along!

[PyMOL] lines same color as background
Hello There, I have this geforce4 ti 4400 with the latest nvidia drivers and xfree86 4.2 Problem: The lines are always colored the same color as the background. If I change the background to white the lines become white. all other representaions (sticks, spheres surface) work fine. So as a workaround I am using stick_radius really small but this is not the same, lines are way better for interactive work. Weird thing is, the same happens under Win2k (dual boot machine here so exactly the same hardware). More weirdness: also happens with Ono under both OSes. My feeling is that this has to do with the z-buffer/fog thingy. I did run a program drawing (GL_LINES) with GL_DEPTH_TEST enabled and that worked fine. any clues?
