The kimpanel's input window reach the edge of the window, it will cause some blinking around the panel.

Here is a patch for fix this problem, the problem seems cause by using different api while get the bound of the screen. In 
KIMLookupTable::updateSpotLocation, it uses screenGeometry() and in KIMLookupTable::resizeEvent, it uses availableGeometry(), which seems to contain the size of the panel.
