Public bug reported: Binary package hint: xfwm4
With compositing enabled and WM tweaks working, if screensaver starts and then exits (i.e. mouse moves) then the active window display is not restored... instead black. If no window is active the desktop fails to repaint. ** Affects: xfwm4 (Ubuntu) Importance: Undecided Status: Unconfirmed -- black active window when returning from screensaver https://launchpad.net/bugs/64115 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
