Title:
Screens go into flicker cycle after going blank with external
monitor(s)
Status in Mutter:
New
Status in mutter package in Ubuntu:
Incomplete
Bug description:
This happens whenever screen goes blank after inactivity with external
monitors.
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:

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.
