Greetings; Please see this bug report: <https://bugs.freedesktop.org/show_bug.cgi?id=35452> It turns out that the radeon driver is not the only victim, the nvidia driver suffers also, and there may be others. Symptoms with the nvidia blob are that black areas of the screen are contaminated from playing a news story. The contamination is stationary, disappears when the terminal window is moved so the screens background image covers the area, but come back when the terminal windows black background again covers the area. Here, it seemed to bother the bottom half of a 1680x1050 screen. Black areas in other apps, such as the html status bar of kmail, or the black patterns of the card faces in kpatience are also rendered rather yucky. We can fix it with: Section Device Option "NoFlip" "True" in the xorg.conf file. There is a patch linked to in this bug-report, which also fixes it, but its an unruly hack according to the X folks. Can this be investigated please? It seems to have become a problem of a far greater frequency of occurrence somewhere around 4.6.2, and has forced me to reboot to clean it up several times over the recent week. Thanks. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
