Crash while attempting to move pixels with split editor views #299

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. New image
2. Split view at least once
3. Select an area in either view
4. Attempt to move the selected area from the OTHER view.
5. Access Violation!

What is the expected output? What do you see instead?
Expect to be able to move the selected area from any view arbitrarily.

Something else hinky happens leading up to this error.  If you move the 
selection around in the original view, at least one of the other views will 
show the transform handles but doesn't update the screen correctly, you can see 
the trails from where you moved the selection, unless you move the selection 
back over the trails (erased by the moving pixels themselves).

Tested with up to three views, in which case one of the views exhibited the 
trail behavior, the other just shows the moving pixels without the marching 
ants from the selection.

Haven't looked too deep into this, just made it happen over and over until I 
had a handle how it was happening.  Upon reflection this might actually be the 
same thing that's happening in issue 209.  It's also not the first problem 
relating to multiple views either.

Please use labels and text to provide additional information.
