If you reinstall with "quick instalation": bash -c "$(wget -qO - https://github.com/poppadum/dynquee/raw/main/install/install.sh)"
The process add a new line in /etc/X11/xinit/xinitrc, but it doesn't delete the existing line, and it causes problems in EmulationStation, and displays screens on top of each other if in previous installations you had selected other screens as primary or marquee.
