Public bug reported: since the upgrade of gnome-session from 3.25.90 to 3.26.0 I observe weird visual phenomena.
1. Icons in the task bar disappear (and only appear after logout/login) 2. Windows get drawn with black margins and sometimes with black canvas (gets away after a second or so) Issue can be related to upgrade of libmutter (libmutter-1-0:amd64 3.25.91+20170902~ce515c5-1ubuntu1 -> 3.26.0-1) ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: gnome-session (not installed) ProcVersionSignature: Ubuntu 4.13.0-11.12-generic 4.13.1 Uname: Linux 4.13.0-11-generic x86_64 ApportVersion: 2.20.7-0ubuntu1 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Fri Sep 15 12:33:43 2017 InstallationDate: Installed on 2017-09-05 (9 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Alpha amd64 (20170902) SourcePackage: gnome-session UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: gnome-session (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug artful wayland-session -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1717486 Title: gnome visual issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1717486/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
