Title: Focused window is not always brought to front Status in xorg package in Ubuntu: Confirmed Bug description: The following steps will systematically reproduce the issue. Terminal is only an example, you can do the same with any other application that can open multiple windows. - open three terminal windows - hit Ctrl+Super+D to show the Desktop. All windows disappear as expected - click on the Terminal icon in Launcher. One of the three windows is selected and brought to front as expected - click on the Terminal icon again - when presented with the three miniature windows, click on any of them except the one you previously selected Expected result: the selected terminal window should get focus AND be brought to front Observed result: the selected window is given focus but is not brought to front. Instead, another random one of the three is brought to front. The mere fact that the focused window is not the one on the top of the stack (i.e. the one most on the front) is in itself an inconsistency that should never exist and should be forbidden at the lowest conceivable level. Note that this is a HUGE SECURITY ISSUE and as such should be marked as critical. You can be typing (or sending keystrokes) into a window without even seeing it. Since one window is brought to front, you may not realise that it is not focused (though you can tell the difference if you look at it carefully enough), and hence you may for example hit several keys including Enter thinking that the selected windows is not responding, while infact your keystrokes are all processed by the invisible focused window. You may do random stuff on the invisible focused window. You could *literally* (and I'm not abusing the word "literally") wipe out your hard drive or publish your password on Facebook; or more likely, delete files or do all kind of irreversible damages to some document of yours. Note that I reported a somewhat similar issue where a random window is focused instead of the clicked one but that's a different bug (it still happens, but I don't know how to reproduce it systematicall), and another one regarding the focused window not having the title bar and borders, but that's different too and that particular one seems to be fixed.
