RE: [PyMOL] lines same color as background

[DeLano, W. <wa...@su...>]

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=3D0) or smoothing (set line_smooth=3D0), 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!

Cheers,
Warren
