Known Issue
Due to bugs in Nvidia drivers, installing and running Shiny OS on a Nvidia laptop with hybrid graphics on an external monitor can cause high CPU usage. Run nvidia-settings and set Prime profile to performance mode to avoid this. Other issue with NVidia is Wayland will not be used and the default movie player, Totem, may crash when started on XOrg. Installing mpv for playing videos is then recommended (sudo apt install mpv)
