<pre>Once again KDE/Qt and kwin amaze me by their inefficient rendering. At least it
found a bug in my code. The issue here is that kwin continues to render the
static composited image (that is the cause of the black flash), and the DDX
failed to undo its shallow copy of the scanout used by ksnapshot for its region
selection GUI.
