Description: do not set Qt::ToolTip flag for QShapedPixmapWindow
This hint is not really needed in the first place and only causes
problems in some environments.
.
For example in KDE, the compositor animates changes in position and size
for all ToolTip windows. However, this is not wanted here because we use
this window as a thumbnail for a drag-and-drop operation.
Before this patch the dragged element would lag significantly behind the
cursor. Now it works as expected, i.e. the dragged element follows the
cursor immediately.
