Please ask on a forum for help/support. This is a configuration issue, not a bug.
If you cannot alt+tab between windows, no WM is running - try to start kwin from konsole and see whether it segfaults (you'd get a crash dialog) Otherwise run "kcmshell4 kwincompositing" and check whether there's a blind rule (matching all windows) that triggers the fullscreen mode. If kwin segfaults, open a bug from Dr. Konqui (including the backtrace) otherwise move to forum.kde.org since it will be required to figure the layer of the problem first.
