That’s on the 7840 without dGPU. I’ve had problems with screen flickering on Ubuntu 22 half a year ago, running Wayland and Gnome. All monitors (internal and external) would go black for a split second before returning to normal. Switched to Tumbelweed and never looked back.
As far as I know, only X11 is active. I may have KDE and/or Gnome apps installed, including their dependencies, but the desktop environment is XFCE4.18
