Colleagues, I noticed the following problem on fedora core 3 boxes (i386
and x86_64), using either pymol 0.96 or 0.97 (precompiled linux tar ball):
The cartoon representation of PDB entry 1NXC (approx. 400 residues, mainly
helical) appears normal for about half of the structure whereas the other
half can be seen as shadows covering the "normal" part of the structure
depending on the model's orientation. Upon rotation, the "normal" half
remains with the same part of the structure. That means, in a certain
orientation the "normal" half covers the "shadow" half. In another
orientation, the "shadow" half would cover the "normal" half and in yet
another, the left side of the model disappears in the background whereas
the right side appears normal.
A smaller molecule appears to behave "normally".
pymol 0.97 works as expected on Redhat 9.0 and I *believe* I did not
experience the problem on Fedora Core 2 (x86_64).
For X, I am using the radeon driver supplied with Core 3.
I strongly believe that the problem was introduced by my Fedora core
upgrade, but I have no idea what ultimately causes the phenomenon.
Has anyone else any comments?
