Hello,

The only time I've seem this kind of bug before is when the graphics 
hardware is flakely.  Since it works initially, it might be failing after 
the graphics chip warms up, so it could be due to a broken fan in your 
computer, or poor airflow, or a bad graphics chip, or bad graphics 
memory, or ....

Since this still could be a graphics driver bug, please report this as a 
bug using chimera's "Report a Bug" dialog found in the Help menu.  That 
will tell us about your actual graphics setup and let us make specific 
recommendations on how to upgrade your graphics driver.  But from your 
description, I suspect this is a physical problem with your computer.

 	Good luck!
