Full screen apps turn grey.

easy repro:
I was trying to work around #43
But this will happen in any fullscreen game, if a game can be set to "borderless windowed" it seems to work, but imv seems to invoke "true full screen" with or without the -f flag, and breaks this script from being useful:

        OUTPUT=$(swaymsg -t get_outputs | jq -r '.[] | select(.focused).name')
        FOCUS=$(swaymsg -t get_tree | jq -r 'recurse(.nodes[]?, .floating_nodes[]?) | select(.focused).id')
        grim -t ppm -o $OUTPUT | imv -f -w screen-shot - &
        IMV_PID=$!
        grimshot --notify copy area
        imv-msg $IMV_PID=$! quit
        swaymsg "[con_id = $FOCUS] focus"

What compositor are you using?

I have the same issue on Sway 1.9. Window loses focus and all popups are gone, as well as fullscreen apps like games turning black.
