I have updated yaru-theme from focal-proposed. I confirm that together with gnome-shell-extension-ubuntu-dock previously updated from proposed this fixes the issue for me in focal.

This bug applies in the cases of left and right positions of the dock and there is no this bug in the case of bottom position. This issue is very annoying since the mouse pointer runs at the very corner of the screen in vast majority of cases as you intent to press the Show Apps button. [ Test case ] - Ensure the dock is positioned on the left side of the screen - Move the cursor at the bottom left corner - Clicking should open the app grid [ Regression potential ] Dash has missing padding ---- ProblemType: BugDistroRelease: Ubuntu 20.04 Package: gnome-shell-extension-ubuntu-dock 67ubuntu20.04.3 ProcVersionSignature: Ubuntu 5.4.0-24.28-generic 5.4.30 Uname: Linux 5.4.0-24-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Thu Apr 16 20:34:32 2020 InstallationDate: Installed on 2019-04-25 (356 days ago) InstallationMedia: Ubuntu 19.10 "Eoan EANIMAL" - Alpha amd64 (20190425) PackageArchitecture: allSourcePackage: gnome-shell-extension-ubuntu-dock UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/dash-to-dock/+bug/1873321/+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
