    The advantage of the backclear patch over the no-backfill one is that backclear replaces the occasional patches of garbage (uninitialized memory) with patches of black, addressing the security concerns (chance of seeing screen data from a previous session or user) which prompted removal of the no-backfill patch in the first place.

    If the no-backfill patch is working for you then there's probably no compelling reason to change.

      To avoid this bug in karmic use the https://launchpad.net/~k0ekk0ek/+archive/ppa, in lucid you can use https://launchpad.net/~info-g-com/+a...-xorg-1.7.6-gc

      As bridgman wrote, at the moment is no reason to change back. I'll keep the package in sync with the latest servers until its finally fixed... Hoping soon. For more information you should read lp #351186 and its successor.

        Thanks, I'm using ur patch from the ppa already. For me it works fine, my only complaint is some minor artifacts that appear briefly during some compiz animations. For example some weird dots near the top of the window when it's maximized. Everything is fine other than that.

          I know. I think its because near the top there are two Sections, first the window title, then the section with the menus. Probably you see the normaly not visible border between these sections in Actions like miniizing, maximizing or wobble. No clue about it. To verify that, you might use another scheme for testing purposes.

            Have take a second look at this. It look like rounding errors ins Compiz and occurs also when not animated

                  You got it exatly right. It's that in-between section/line that I'm seeing. Also I checked out your screenshot and I get that too. I don't know if it has to do with compiz or the no-backfill patch.
                  When I change the compiz animation quality settings to "best" it's much more prominent than when I have it set to "fast".
                  Anyhow, I really like the new ubuntu theme so I'd rather use it with these minor annoyances than use a different one that would cover up these artifact related problems.

                    Ok, i have check these behavior back on another machine. It's my server with an Intel G43 and an unpatched xsever. Compiz on. Wobbly on. It has the same artifacts as you described. So i would say, the error is not on Ati nor the patch. I would say, it's compiz.
