The new Unity lock screen doesn't have problem with application grabbing the mouse (indicators, menus, etc.) but only if the mouse cursor is outside of that menu. When you open menu of application (global or LIM) or indicator then move the cursor outside of that menu and application the screen will blank off and lock.
When you have open indicator or menu of application (global or LIM) and mouse is focused on that menu the screen will not blank off and of course it will also not lock. This is still a bug in gnome-screensaver and X server just like the one that you linked because the new Unity lock screen still uses gnome- screensaver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1292446 Title: lockscreen: on autolock on suspend the fade does not complete before suspend leaving desktop partially visible for a short period on resume To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1292446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
