I am not sure why this is happening without more information. I am wondering, as Ethan had suggested, if this is due to Wayland.
Can you give a complete description of your configuration? Including but not limited to model of rpi, version of raspian, etc. I have a couple of rpi models but I would like to duplicate this issue completely if possible. It’s also possible something is stealing focus elsewhere.
