Stretch contrast - preview and final image don't match depending on size

Hi,

I just found out that the preview "try" and the final image can differ
severely if the real image size differs from the screen size, especially
if I push the values a bit. If I resize e.g. the picture to 1000x1500
and stretch then, everything is fine, but with e.g. 3000x4500 there's a
big difference to the preview. I'd suggest to calculate the preview on
the original image.

found with digikam/kipi 1.3

thanks

just found out that it works fine if you set the zoom to 100% before you
stretch - then preview matches final image
I'd call that a workaround though
