I used to use separate desktops for some applications like konsole or emacs.
I tune window specific settings to run each of these apps on a separate desktop
in a fullscreen mode.
Now I've upgraded from etch to lenny and noticed a behaviour change which
makes me upset. Following steps should reproduce it:
1) Run konsole and press ctrl-shift-F to switch to fullscreen view.
2) Switch to another desktop.
3) Run another application, e.g. konqueror.
4) Switch back to the desktop where konsole is running.
Notice? The kicker is on top of the fullscreen konsole, though the focus is
in the konsole window. You can try to explicitly bring focus to the konsole
window, but kicker will stay. The only way to get rid of kicker is to
click into the konsole window, then switch to any other desktop and switch
back again.
Such behaviour doesn't depend of the app running in fullscreen mode. Tested
with konsole, konqueror and emacs.
This is either kwin's bug or kicker's one.
