--- Comment #8 from Anton Gubarkov <anton.gubar...@gmail.com> --- Well, on my Haswell i7-4900MQ the preview is not really live :-( When I move the corners, the video image transformation follows approx 1 frame per second (even on nearest neighbour). And I can't see the lines indicating the source aspect ratio. I think, if you could make the image being transformed a semi-stransparent, it would be much more convenient. As an alternative, make a wireframe (w/o live update of the image) and allow it to be really live. -- You are receiving this mail because: You are watching all bug changes.
