I use gnome-shell with focus-follows-mouse, which I enable using gnome-tweaks. I configure Alt-DownArrow to "Lower window below other windows". When I lower the current window below others, the focus fails to shift to the window now on top as expected. Reproducible: Always Steps to Reproduce: 1.Enable focus-follows-mouse 2. Add shortcut for lower window below others 3. open several windows 4. lower top window below others Actual Results: The focus remains with the lowest window. I can see this by trying to move focused window to another virtual screen, or raise the current window above others. Expected Results: Focus shifts to the top viewable window below the mouse. This used to work in F37. This works in Ubuntu 20.04.
