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.
