Does anyone notice weird visual artifacts in X with recent distros? I see it in both Centos and Ubuntu. For instance, when I alt-tab in KDE, the list of windows doesn't appear, or when firefox refreshes the screen, there is a noticeable delay and diagonal streaks of color like a messed up pix buffer for a flash of a moment. In centos, it got particularly bad, where I could only redraw firefox windows by resizing them, otherwise the content remained when I switched tabs. It might happen in other apps, but I really only use firefox and Konsole on that machine. On Ubuntu, the screen saver will also sometimes not blank out the screen, so I will see a stale 'screenshot' of the desktop, when in actuality, there is a dialog asking for my password. In short, it seems that some kind of video buffer, somewhere in the system, is acting goofy. Restarting X seems to help, but I only do that a few times per year if I can help it. I'm suspecting this has something to do with the new 3d desktops. On both machines, I had compiz and/or beryl installed in the past, though I removed (or tried to remove) both. I had never seen these artifacts in years past, but now it happens on two different machines, each with a different Distro. Anyone else see this? Jeremy
