Forwarding this bug from Ubuntu reporter Philip Falkner: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/446425 [Problem] After upgrading to mesa 7.6 (from a mesa git snapshot from mid-August), 1-pixel wide artifacts are displayed on the screen. These disappear on screen repaints. [Original Description] Starting today, Oct 8, with Kwin compositing active, I get 1-pixel wide artifacts all over the screen. When a window disappears, the very right-most and bottom-most lines of it remain. Sometimes when scrolling in Konqueror, a line from somewhere else in the web page will "stick" at the bottom of the web view (above the status bar). The bouncy cursor icon when launching a new application leaves bits of itself behind. All of these artifacts disappear when that part of the screen is repainted (e.g. moving a window over the area, activating the present windows effect). Didn't happen before rebooting this morning, so I'm suspecting mesa 7.6.0.

I'll test reverting that patch as soon as I can.
