I just installed Lubuntu Precise final in order to perform Lubuntu i386 Quantal upgrade testing and even the Lubuntu i386 Precise final will display this behavior. If you don't "drag" the installer windows around you can see still see "window-over-window" behavior.
Since a picture is worth a thousand words I'll repeat with an Lubuntu Precise image and show you very soon ;^) I somehow doubt this is a true Xorg bug ............. maybe more related to the gtk2 -> gtk3 switch ???? I really don't think it's a serious issue, just cosmetic. ** Changed in: xorg (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1057120 Title: Ubiquity screen problem during install.
