- Subject: kwin: eats all keystrokes after switch desktop and requesting alt-tab

Package: kde-window-manager
Version: 4:4.3.1-1
Severity: important
Context: this is a machine with several users (in several
simultaneously-running sessions on the same seat) and "only" 1.5GB of
RAM, so things get swapped out before one user comes back to the seat
while others use it.
In my session I have one "main" desktop with light apps, and another
one which holds a handful of firefox windows. When I switch to this
FF desktop, it takes some time for it to get responsive - I am not
sure it is only a matter of FF being swapped out, since even the
active window frame drawn by kwin does not get drawn before a couple
of seconds.
Now if I do not wait for the "desktop switch" to "stabilize" after
Ctrl-F2, and start going Alt-TAB-TAB in the hope to reach a particular
FF window rapidly, it sometimes happen that the keyboard stops
responding:
- no wm shortcuts (alt-tab, ctrl-Fn, etc)
- no key event receieved by the active window
- still able to switch desktop and apps with the mouse
- still able to Ctrl-Alt-Fn to another VC and use the keyboard there
Now if I "killall kwin" and switch back to X, I can then use the
keyboard again and restart one from my xterm, and all is good (until
the time I get impatient again).
What kind of additional information would be useful here ?
