I can confirm this bug, and the workaround with gsettings works. I encountered this same bug on two different machines on 18.04, both updated multiple times daily, one with a Logitech mouse + unifying receiver and the other with a standard Apple wired mighty mouse, on both Wayland and Xorg. I think this bug is quite universal, the Logitech mouse machine uses Xorg daily with an HD 5570 and the mighty mouse machine uses Wayland daily with a GTX 760 (nouveau).
Since it occurred with a wired mighty mouse (and a dongle wireless USB mouse), I don't think it is specific to bluetooth mice. It also occurs when scrolling horizontally with the scroll "ball" that can scroll in all directions. The same issue also occurs for me when scrolling horizontally or vertically on the popup menu from single-clicking an app with multiple dots/instances, by that I'm referring to the menu with all the instances listed (like gnome-terminal) and that allows one to choose which one to bring to the front. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717486 Title: icons missing after 2 fingers/horizontal scrolling on the dock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1717486/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
