Can't reproduce this, but your sample code looks like you made a standard

Here you flip 'img' and the flipped surface is stored in 'imgA'

Here you again flip 'img' and the flipped surface is stored in 'imgB'

Now consider what you've done was only flipping the original image at
the Y axis. And the result is obviously correct

It does :)

imgA is not flipped at all. neither is imgB flipped. You only flipped
'img' twice.

Note that you could have noted that everything works correctly in that case :)
