kwin/tabbox/switcheritem.cpp
Thomas Lübking f96836b2df update SwitcherItem::screenGeometry when showing
not everytime the current screen changes.
a) that pollutes the geometry when the tabbox is invoked
b) it's insufficient for "Active Screen follows mouse" (the default)
c) less overhead (ok: "on multiscreen")
