Screen fails after unplugging HDMI or turn of after suspend

cn flag

What's up?

Since I have reinstalled ubuntu 20.04 when I plug or unplug my HDMI cable (not when I turn on the pc with it connected, only when I want to change), if I wake up the laptop from suspend or if I change the resolution. Important points of this issue is, if i have plugged the hdmi, that screen works perfectly while my laptop screen is glitching and it doesn't matter if I'm using xorg or wayland, the problem is in both servers. I uploaded this image so you can know who the laptop screen looks.

I have the lenovo yoga 13" c930 with amd ryzen 5700u and radeon graphics

this is how it looks
