I see corruption as well, when I right click on the desktop I often get this result:
http://i.imgur.com/Ou9QJ.png As you can see, parts of the window and panel aren't redrawn (and they probably shouldn't be, the menu never covered the window nor the panel). The artifacts persists until I force the panel and window to redraw by moving them around or switching workspace. It seems to happen more often when I right click in the lower left corner of the desktop. I also often get some strange results when a window is set to "always on top" and "visible on all workspaces" and I switch workspace: http://i.imgur.com/Vdr0x.png The problem completely disappears when I start a compositing manager. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/740387 Title: graphical corruption with multiple drivers and classic desktop -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
