The bug is being tracked in freedesktop.org's bugilla: http://freedesktop.org/bugzilla/show_bug.cgi?id=474 And relates to pixmaps being cached but not cleared out when the memory is needed for the XVideo extension. There is a workaround suggested in the bugzilla page, adding: Option "XaaNoOffscreenPixmaps" to xorg.conf, giving something like this: Section "Device" Identifier "Videocard0" Driver "mga" VendorName "Videocard vendor" BoardName "Matrox Millennium G550" Option "XaaNoOffscreenPixmaps" EndSection This seems to work for me... though obviously it is just a workaround and not a solution.
