I disabled the Ubuntu Dock extension using the Gnome Extensions app and tried to reproduce the bug, and the bug didn't happen anymore. When I installed the Dash to Dock extension by the Gnome Extensions site, and tried to reproduce the error, nothing wrong happened.
I think that the bug is caused by the dock, and the version 68 of Dash to Dock fixed this bug. The Ubuntu dock is still in version 67. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1870847 Title: App grid has too many page dots on right Status in GNOME Shell: Unknown Status in gnome-shell package in Ubuntu: Triaged Bug description: When I click the "Show Applications" button in the lower left, it brings up a matrix of application icons, which takes a page and a half. There should be two dots on the right to match the two pages, but instead there are * dots. Moving up and down, the first and second dots highlight to show which page I am on. But only the top dot, and the bottom two, can be clicked on to change the page.
