Lately I've been seeing windows get corrupted suddenly. I took a snapshot of one and you can see it at http://www.allmanpc.com/video_display_error.jpg If I minimize/restore the window it will (so far) re-display correctly. Moving between workspaces (I have 4) doesn't fix the problem. If I mininize the window and hover over the task bar area for the window it'll show me a small preview of the window and it will still look corrupted. If I restore the window it will start to display corrupted for a split second and then appear to repaint correctly (it's hard to tell--it's very fast). Has anyone else seen this? The overall desktop displays fine. The problem is limited to windows. It doesn't appear to be an app-related issue. I've seen this happen to OpenOffice, Evolution and Opera windows (and maybe others--I don't recall). My /etc/X11/xorg.conf file is very tiny: # Xorg configuration created by livna-config-display Section "Files" ModulePath "/usr/lib/xorg/modules/extensions/nvidia" ModulePath "/usr/lib/xorg/modules" EndSection Section "ServerFlags" Option "AIGLX" "on" EndSection Section "Device" Identifier "Videocard0" Driver "nvidia" Option "AddARGBGLXVisuals" "True" EndSection Section "Extensions" Option "Composite" "Enable" EndSection I don't know if this is an X and/or KDE and/or nvidia problem. This just started within the past week or two. I haven't changed any nvidia, X or KDE settings lately. I've re-booted the laptop a few time in the past few weeks so it's not an "update needs a reboot" issue. I've looked through ~/.xsession-errors but nothing looked obvious like "error displaying window." One observation: the windows which are corrupted always look about like what the snapshot image I mentioned earlier looks like. It's not random. It looks like that green vertical bar pattern on black every time. My system (which is up to date as of a few days ago): Dell XPS 1710 Video H/W: nVidia GeForce Go 7900 GTX Kernel: 2.6.30.5-43.fc11.i586 Desktop: KDE xorg-x11-drv-nvidia-libs-185.18.36-1.fc11.i586 kmod-nvidia-2.6.30.5-43.fc11.i586-185.18.36-1.fc10.i686 xorg-x11-drv-nvidia-185.18.36-1.fc11.i586 akmod-nvidia-185.18.36-1.fc11.i686 kdebase-4.3.0-1.fc11.i586 Anyone have a clue what might be causing this? -- Mark C.
