On a second machine also running current focal (it's not convenient to do it on this one right now) I disabled extensions via the Extensions pref panel, deleted my user extensions, and removed gnome-shell- extensions.
There were a handful of extensions still on disk whose packages have a lot of reverse dependencies, which I didn't remove. [clammy(~)] gsettings get org.gnome.shell enabled-extensions @as [] [clammy(~)] ls ~/.local/share/gnome-shell/extensions/ [clammy(~)] ls /usr/share/gnome-shell/extensions/ desktop-icons@csoriano [email protected] [email protected] [clammy(~)] _ Then I rebooted and logged back and and reproduced the problem successfully as per example 1 above. ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => New -- 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/1869261 Title: popups move to top left of window when opened Status in gnome-shell package in Ubuntu: New Bug description: When I open a popup selection menu or a drop-down menu from a legacy menu bar, it behaves oddly. First, it appears in about the right place. Then it jumps to the top- left of the owning window, and the items scroll off. I can navigate it with the keyboard and mouse and it's almost usable. When the popup is closed and I try to open it again, it refuses to appear until I quit the appliation and reopen it. Example 1: * open Settings * select Default Applications * click one of the options to pop up its menu * it may open in the right place, or immediately jump to the top left of the window * if it opened in place, attempts to interact cause it to jump to the top left of the window * close the popup, and it can't be opened again (at least not visibly) * close the app, reopen it, and the process can be repeated Example 2: * some apps with legacy embedded menu bars also behave weirdly, e.g. Quod Libet's menus will jump around similarly quite often, but not entirely consistently I assumed gnome-shell is responsible for positioning and rendering popups, but maybe this is a GTK+3 bug?
