More steady increasing, even after killing a silly screensaver that was leaking pixmaps. The slight dip, and the smoother line after is what resulted from that.. No idea what happened around the spike though. http://strangesoft.net/gem_objects_plot5.png So in both the gl and xrender modes for kwin's compositing, I'm getting some serious gem_objects leaks. Another couple days and it'll probably crash again. -- Thomas Fjellstrom tfjellst...@shaw.ca _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
