Issue:
Using the new "Allow Tool Recording" feature in CS6 allows you to record brushstrokes. However, this functionality is broken with the clone and healing brush tools.
Description:
When recording use of the clone tool in an action with "Allow Tool Recording" enabled, replay of the clone tool gives "offset" results.
Changing the zoom level, or moving the document on the canvas will give similar but different incorrect results on consecutive replays of the same action.
Or, put another way - the action clones from the wrong place when replayed.
