The default screenshot doesn't work for me.

I installed Hyprland v4 now and the screenshot doesn't work for me. So I'm using the script below for the screenshot
timestamp=$(date +"%Y%m%d%H%M%S")
screenshot_file="$pictures_dir/screenshot_$timestamp.png"

Use slurp to select an area for the screenshot

selection=$(slurp)

Use grim to take the screenshot

grim -g "$selection" "$screenshot_file"
