Public bug reported: The composite overlay window is only allocated once, at server start up. Should the user change the screen layout using xrandr, the COW will no longer cover the whole framebuffer. This means that when the user is running a composite manager using the COW (compiz, metacity and I think KWin4) no windows will be drawn on areas not covered by the COW - for example, the second head if the user has run "xrandr --output DVI-D-0 --right-of LVDS-0".
This Xorg bug http://bugs.freedesktop.org/show_bug.cgi?id=4394 covers this in more detail, and has a patch which is applied to Xorg git which resizes the COW on xrandr changes. I'll provide a debdiff against our xorg-server applying this patch. ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: New -- xrandr changes break composite on 2nd head https://bugs.launchpad.net/bugs/199700 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
