Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

This one contained four images vertically oriented, so to line them up, I copied them and rotated them 90 degrees counterclockwise with eog and saved through eog, and then pointed Hugin at the rotated images (Possibly Hugin could make a vertical panorama without my doing this, but I didn't try...) After the panorama image was complete, I copied it and rotated it into a vertical orientation again (90 degrees clockwise) and saved through eog. Imagine my surprise, when I looked at the final image, and saw a strip of pixels on the right that didn't look right. Upon closer inspection, I found that they seemed to match the pixels on the left edge. When rotating, the image appears correct. It is only after saving, and re-invoking eog on the image that the problem is visible. It is not a display problem, as the copied/moved pixel columns show up when the image is shown with ImageMagick, and GIMP. With GIMP, by blowing up the display to 400%, and watching the pixel coordinates as I move my mouse from the left to the right over the false pixel columns, it appears that the number of pixel columns copied or moved is 7. Upon further research, When I have GIMP blow up both images equally, it seems clear that the pixel columns are being cut off from the left side of the image, and attached to the right side. (In the attached images, if you look at the "C" on the left (about 75% of the way down, at the edge), you will see that it lines up almost exactly with the edge of the image, yet in the horizontal image, there is a gap between the edge and the "C" (that appears also to be about 7 pixels wide)) ------------------------------------------------------------------------ scott@scott-Asus-M2N68-AM-PLUS:~$ uname -a Linux scott-Asus-M2N68-AM-PLUS 4.13.0-32-generic #35-Ubuntu SMP Thu Jan 25 09:13:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux scott@scott-Asus-M2N68-AM-PLUS:~$ lsb_release -dsc Ubuntu 17.10 artful scott@scott-Asus-M2N68-AM-PLUS:~$ echo $DESKTOP_SESSION QLubuntu scott@scott-Asus-M2N68-AM-PLUS:~$ eog --version GNOME Image Viewer 3.26.1 ------------------------------------------------------------------------- ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: eog 3.26.1-0ubuntu1 ProcVersionSignature: Ubuntu 4.13.0-32.35-generic 4.13.13 Uname: Linux 4.13.0-32-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 CurrentDesktop: LXQt Date: Mon Jan 29 20:54:14 2018 InstallationDate: Installed on 2017-11-06 (85 days ago) InstallationMedia: Lubuntu-Next 17.10 "Artful Aardvark" - Beta amd64 (20171014) SourcePackage: eog UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eog/+bug/1746146/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
