Dear Maintainer,
   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
	Standard install of kde-plasma-desktop. I have two screens of equal
        size configured with aticonfig --initial=dual-head which works as
	expected (can move the mouse between the screens).
   * What was the outcome of this action?
	I can not move windows between the two screens. Starting
	an application puts the window in the left screen, and
	I can not drag it to the right screen. I turned off the
	maximize/alignment magic that happens when you come close to
	a screen border while dragging windows.
   * What outcome did you expect instead?
	The window to be moved.
