Hi Dima,

   As Greg mentioned the problem is the poor state of Intel graphics 
drivers on Linux.  I'd try a Chimera 1.4 daily build as he suggests.  If 
that does not help you might be able to improve the slow surface and 
mesh rendering by turning off use of OpenGL vertex buffer objects using 
the Chimera debug graphics dialog.


You would start Chimera with "chimera --debug-opengl" and switch of 
vertex buffer objects in the dialog that appears.
