--- Comment #10 from Adolfo Rodrigues <adolfotreg...@gmail.com> ---
Gwenview not showing the image correctly as one would expect could lead to
erroneous monitor corrections. Gwenview should show the image exactly like
any other image viewer , even a browser shows it correctly!! I just
reported the situation that WILL at some point cause someone issues
unnecessarily. Give a option , a disabled option, that makes Gwenview act
like the others.
