Closing this bug. PLEASE KEEP IT CLOSED! This is fixed in 4.11 by the switch to KScreen. (I close it as "fixed in 4.11.0" rather than "unmaintained" so that it shows up in the list of fixed bugs in 4.11.0.) If you are still seeing related issues WITH 4.11.0 OR NEWER, please file a new bug against KScreen. If you are still using kde-workspace 4.10.x or older, YOUR ANCIENT KDE WORKSPACE IS NOT SUPPORTED ANYMORE, bugs will not and cannot be fixed in it.
