Hi,
This seems to be an issue between iChat amd Messages involving the update to Apple Remote Desktop.
Apple Remote Desktop is the "engine" behind iChat's and Messages' Screen Sharing.
(It is also involved in Remote Management or Screen Sharing as listed in the Sharing section of the System Preferences {it cannot be both at the same time}).
The "fix" seems to be to alter one ends display resolution to "match" the other end.
The issues was first documented before the date of the Apple Remote Desktop Update version 3.6.1 but it is unclear if this fixes the issue which starts with version 3.6
Some people have used Time Machine to backstep the Apple Remote Desktop folder to pre 3.6
