I forgot to say this: for my screen is not perfect, I couln't directly notice the "weird thatched-pattern". In order to reveal the artifacts, I set the bucket-fill tool's threshold at 0 and then randomly clicked the area. If the scaling went fine, the whole image should be filled. When resizing at 1/5 and 1/6, only bits of the picture or the pattern itself would be filled.
So, in my case, I was not able to see the artifacts because of my screen's quality and settings, but these artifacts did exist. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/648379 Title: Artifacts when scaling down with Sinc Lanczos3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/648379/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
