I don't see many people commenting who use the open driver, and no Karmic users. I have an old Radeon 9600 Pro with the open driver. I've experienced the same behaviour described here: huge lag and high cpu usage by xorg during unminimising, maximising, unmaximising and generally resizing windows. Felix Kuehling's patch fixed these problems although I'm not sure if X+Compiz is working as smooth now as it did on Jaunty. What I haven't yet found an explanation for is that these problems only appeared after moving to Karmic (fresh install) while the no-backfill patch is supposed to have already beed dropped in Jaunty. Other than the speedup, I can see another effect of applying Felix Kuehling's patch: when unminimising Thunderbird window, the two panes showing folders and message list appear black for a short time showing their contents. As for memory leaks I haven't yet tested long enough to tell.
