We have seen this before. It is a bug in the old Mesa OpenGL library
that comes with your Linux distribution. The bug is specifically in the
use of a high performance OpenGL feature called vertex buffer objects.
The solution is to install a graphics driver from the video card
manufacturer (nvidia or ati/amd). This will also give 10x to 100x
faster rendering because the manufacturer driver will use hardware
acceleration where Mesa does all graphics calculation in software. See
our graphics driver bug web page for more details.
This bug is not specific to SPIDER maps and will effect all Chimera
surfaces. It did not occur in old Chimera versions which used older
lower performance rendering methods.
