Comment 1 Alexander Nyßen

2015-08-21 05:54:23 EDT

It seems this happens because the commit() operation of the FXResizeShapePolicy of the F-Dot-Shape is committed twice, i.e. from the FXRelocateLinkedOnDragPolicy of the F-Shape and from the FXCloneRelocateOnDragPolicy of the F-Dot-Shape itself.

Comment 2 Alexander Nyßen

2015-08-21 06:10:29 EDT

Fixed that FXResizePolicy and FXTransformPolicy (which had potentially the same problem) are now robust against succeeding calls of commit(). Resolving as fixed in 3.10.1 RC2.
