Public bug reported: IMHO the highlighting of the current app on the 20.04 task switcher being dark gray over a black background (see attached screenshot) is nearly impossible to distinguish.
This may be suitable for the "dark" theme variant (people working in darkened rooms) but it should be possible to select a "Default" or "Light" variant that makes this a little more easy on the eye. Attempting to adjust this in gnome-control-panel under Appearance-> Window colors has no effect. Using Tweaks, with the "User Themes" extension, under Appearance -> Themes, selecting "Yaru-light" for Applications and "Default" under Shell exhibits the same behaviour. Interestingly, there are only two choices under Shell: Default and Yaru- dark and switching doesn't change anything. Could the issue be that a Yaru-light gnome-shell theme is missing from the package? I'm still unsure whether this is an install issue with my 19.10 upgraded deployment but having cross-checked the package content, I don't think so. My system is fully updated. $ lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 $ apt policy yaru-theme-gnome-shell yaru-theme-gtk yaru-theme-gnome-shell: Installed: 20.04.4 Candidate: 20.04.4 Version table: *** 20.04.4 500 500 http://ch.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://ch.archive.ubuntu.com/ubuntu focal/main i386 Packages 100 /var/lib/dpkg/status yaru-theme-gtk: Installed: 20.04.4 Candidate: 20.04.4 Version table: *** 20.04.4 500 500 http://ch.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://ch.archive.ubuntu.com/ubuntu focal/main i386 Packages 100 /var/lib/dpkg/status ** Affects: yaru-theme (Ubuntu) Importance: Undecided Status: New ** Tags: focal ** Attachment added: "Task switcher.png" https://bugs.launchpad.net/bugs/1872488/+attachment/5353344/+files/Task%20switcher.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872488 Title: Task switcher current app highlighting - dark gray on black - v. hard to distinguish To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/yaru-theme/+bug/1872488/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
