That is kind of surprising, because the potentiallyLoadFullsize() does not 
(directly) manipulate the view position or zoom level. I'm suspecting that it 
interacts with cropAndScale() and causes that function to misbehave…

Can you try and see what happens if you switch the position of the 
potentialyLoadFullSize() call with the call to cropAndScale(), i.e. what 
happens if cropAndScale is done *before* potentiallyLoadFullSize?


Cheers,
