I've put up with it for over a year now, but it's really started to get on my nerves. I've done some testing and it seems to have been introduced in 6.13.0. If I go back to 6.12.7, everything is fine. I'm using X server 1.7.7 from ports, with EXA acceleration. This happens without a compositor running (kwin/compiz/xcompmgr). In the screenshot, it's just plain openbox. You can see three windows (Terminal, akregator, chrome) as one big giant mess. This happens mostly when moving/resizing windows, but also with scrolling. Running 'xrefresh' will clear the screen and redraw everything properly. But then I move a window, and it happens again. Sometimes it's worse than others. In the screenshot, it's particularly bad. Unfortunately, the developers in #radeon on Freenode don't seem paritcularly concerned as this bug is only present when using UMS (I had the same issue in Slackware at one point when I was using UMS), and UMS is now, essentially, deprecated. There is at least one bug reported on http://bugs.freedesktop.org/ that seems to be related: https://bugs.freedesktop.org/show_bug.cgi?id=27650 Adam
