[Chimera-users] problems display a mrc or ccp4 file

I have seen the sliced bread volume contour surface appearance many
times before and every time it was with Mesa. I've never seen it with
an nvidia driver. The cases I've seen are a bug in the Mesa client-side
library so if you are remote displaying Chimera from another machine
then you will see the problem even if the machine you are displaying on
has nvidia drivers if the machine Chimera actually runs on is using Mesa.
If your case does not involve Mesa at all you should report a bug
using Chimera menu entry Help / Report a Bug... which will give us your
graphics driver info. It is definitely a graphics driver bug and we
like to keep track of which drivers have problems.
