I recently acquired a new machine and found that my previous
coot executables will not run on it, and neither will the 
stable or "nightlies" built for Fedora/RHEL or Ubuntu.
No problem, I thought, I'll just rebuild it from current source.

That worked, but the graphics display speed of the resulting
executable is very slow.  I have not noticed rendering speed
issues with any other programs I am running.

The recent mention here of buggy Mesa versions makes me wonder
if that is what I'm suffering from.
I can't find any likely pointers on the web.  
Does anyone have more detail?  
Is there a work-around?

Since I'm building from source I am perfectly happy to try
patching the Coot end of things if that would help.
