This is a workaround for an apparent bug in mutter but fixing mutter is much more complicated. The Desktop Icons NG GNOME Shell extension is enabled by default on Ubuntu 22.04 LTS so a bug here could make desktops unusable. - --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82.1 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2022-03-17 (75 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Alpha amd64 (20220313) Package: gnome-shell 42.1-0ubuntu0.1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 5.15.0-35.36-generic 5.15.35 RelatedPackageVersions: mutter-common 42.0-3ubuntu2 Tags: jammy wayland-session Uname: Linux 5.15.0-35-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True
