When using KDE, sometimes the rendering of the desktop will become too
large, making things unusable, and requiring a reboot to fix. This
occurs, usually, when I open a fullscreen game such as defendguin or
supertux. In particular, if I've accidentally doubleclicked the mouse,
when only a single click is required to start it from the desktop
launcher (thereby opening two instances of the game, instead of one.)
Is there anyway to fix this? I don't have the same issue when using
other desktop environments/window managers.
