Mutter wakes the display up after lockscreen
When I lock the screen, the display should turn off and stay off until there is some input event. But with my graphics card, Mutter wakes the screen up after several seconds without giving it any input. Then the display is black, but on and consumes energy. It only happens while running GNOME on Wayland, works correctly on X11, so I assume it's a problem in Mutter.
I'm using AMD RX 570 with the radeon driver on Fedora 31, the monitor is connected via HDMI.
