A DESCRIPTION OF THE PROBLEM :
When I run an application with opengl flag enabled, it gradually slows down over time. It usually takes around 2 hours. The same application works fine on windows and mac. I did not see any issue on Mac even when I enabled opengl. At the beginning, it is pretty fast. faster than xrender. But after 1 hour, it becomes extremely slow. New window frame does not show up anymore. Only pop up menu can show up. Mouse tracking is extremely slow. xrender does not have the same issue even though it is slower than opengl at the beginning.


FREQUENCY : always
