When I'm on Plasma and do Ctrl + Alt + F1 (or F2, F3, etc) to switch to a virtual console the problem in the attached picture happens and occurs on every console. And I can't go back to the Plasma session, it keeps showing the pic's error instead, that's the video breaks. I reboot the computer to have the video work again: it starts SDDM then Plasma and if I try to switch to a virtual console the problem repeats.
