Sorry. I'll try to make my point clear. :) With your patch, I cannot start compiz. And without compiz, I can hardly tell if this patch fixes the leakage, because the leakage is noticeable only when compiz is enabled. Maybe I'm in another situation. BTW, I notice that in the file /proc/dri/0/gem_objects, the number of objects always increases, even if I close all the windows. Unless I restart X, this number never decreases. Is that normal? Is it related to the bug discussed here? Thanks for your help. On Fri, Apr 24, 2009 at 5:33 PM,
