I'm having a problem with shapes seeming to be drawn in the wrong location and perhaps the wrong zoom level. The problem seems to correct itself when drawing a selection box, then reappear when the selection box is dismissed. See the screenshot attached.
In the screenshot you will see two shapes drawn. There is actually only one shape (with some sub-shapes) in the diagram, so you are seeing the same shape drawn twice. The larger shape appears when the diagram initially loads, and it appears in the wrong location. As I draw a selection box, the smaller shape appears in the correct location, and where the selection box crosses the larger shape, the larger shape gets apparently erased. When the selection box is dismissed, the smaller shape disappears and the larger redraws, still in the incorrect location.
When not selecting, the pointer icon will change to a move icon when hovered over the location of the smaller non-appearing shape, and will not change to a move icon when hovered over the larger, appearing icon.
