This bug affects me. I am running xnest 2:21.1.3-2ubuntu2.7 When moving a window in the outer X server over the Xnest window, and then moving it away again, the Xnest screen is redrawn (the window manage draws the root widow background, window borders, title bar, and window background) but the applications do not redraw their contents.
For example I have an xterm in the xnest server (white background). When I do as described above I see the xterm with its white background, but the contents is missing. If I move the mouse into the window then I see the cursor but nothing else. If I move another window inside the xnest server onto the xterm and then move it off again then the xterm does redraw its contents (just the part that was "damaged" by the obscuring window. See images.tgz tar xzf images.tgz b1.png - Xnest with 2 xterms and fvwm b2.png - Obscured by window in outer X server b3.png - Obscuring window removed. Note that white xterm has no content now. b4.png - Partially obscured by xterm in Xnest server, b5.png - obscuring window removed. Note that white xterm has been partially redrawn. ** Attachment added: "images.tgz" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/581341/+attachment/5652496/+files/images.tgz ** Changed in: xorg-server (Ubuntu) Status: Expired => Confirmed -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/581341 Title: Xnest application are not asked to redraw their windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/581341/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
