I installed Fedora 34 with Gnome a few days ago, and everything worked fine until yesterday, when I noticed that I wasn’t able to move the icons in the Activities Overview (i.e., Super Key → “Show Applications”) any longer. The applications still open as normal, but I can’t reorder them or group them together anymore - clicking and dragging does nothing. The same goes for the Favorites bar, although I can still add/remove to/from it via the right-click context menu. The problem persists after reboots.
I figured I might have activated a “lock” function by accident, but I haven’t found anything of the sort so far. Anyone have any ideas what could be causing this?
