Hi Mario,

   You should use Chimera menu entry Help / Report a Bug... in order for 
us to provide the best information about your problem.  That will send 
more details about your system configuration -- critically your graphics 
driver version.

   But from what you said the problem is a familiar one, your graphics 
driver has buggy OpenGL "vertex buffer object" support.  You may be 
using Mesa (an all software implementation of OpenGL) and some versions 
of Mesa have this problem.  Your options are to update your graphics 
driver or disable use of OpenGL vertex buffer objects in Chimera using 
the Chimera debug graphics driver tool.


If you are using Mesa (as indicated in the Report a Bug dialog) you will 
get 10 to 100 times faster rendering if you install a graphics driver 
that actually uses the hardware acceleration provided by the graphics chip.
