> .background.decorated:backdrop { This still doesn't feel entirely good. The background can be applied to a window, in which case it needs to be restricted to the .decorated property; but I presume it can also be applied to many other GTK widgets in which case it shouldn't be restricted, at least in order not to change the current behavior because I don't know how to test any change.
So if I'd like to perform the smallest possible change, the smallest possible impact of the change (preferably: no other change than fixing this bug) then I'd need to select for "either window.decorated or something non-window", which I'm not sure how to express in CSS (at least not in a single step). Maybe leave the first block untouched, and then revert its effect in the next rule for undecorated windows (effectively moving the above-proposed user workaround into the main theme, restricted to the element being a window). So the theme itself would go like (the first block is unchanged, the second one is newly added): .background:backdrop { color: @backdrop_fg_color; box-shadow: inset -1px 0 shade (@bg_color, 0.94); } window.background:not(.decorated):backdrop { box-shadow: none; } Dunno how much it makes sense. Would really love to get it reviewed by a CSS expert :) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-themes in Ubuntu. https://bugs.launchpad.net/bugs/1986450 Title: Visual artifact 1px vertical white line right side of the wallpaper with Ambiance/Radiance Status in gnome-shell package in Ubuntu: New Status in gnome-shell-extension-desktop-icons-ng package in Ubuntu: New Status in ubuntu-themes package in Ubuntu: New Bug description: After manually upgrading from 20.04 LTS to 22.04.1 LTS I find that there is a 1px wide vertical white line on the desktop that appears whenever an application has focus. It is on the right side of the monitor, covering the background wallpaper but not the menu. Workaround: in Displays, change scale to something else than 100% and then change back to 100%. That white vertical line will stay at the former 100% window size location until the Settings window is closed. It disappears when the Settings is closed. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82.1 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2018-04-27 (1570 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) Package: gnome-shell 42.2-0ubuntu0.2 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 5.15.0-46.49-generic 5.15.39 RelatedPackageVersions: mutter-common 42.2-0ubuntu1 Tags: wayland-session jammy Uname: Linux 5.15.0-46-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo www-data _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1986450/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
