I switched back to Wayland and 2 external monitors today and the flicker seems to be gone (Ubuntu 23.04 with current updates).

When there is only one external monitor after few cycles the system recovers from the bug. When there are more than one monitors the system almost never recovers until unplugging extra monitor, as shown in video: https://photos.app.goo.gl/td6coEKFQd3DKe9C7 Happens on desktop and login screen. The same result with Wayland and X11. Does not depend on size of the monitor, cable (HDMI or USB-C) or is it connected via USB-C hub or directly.
