redetected. Then bug 2013042 occurs.

Title:
Lockscreen shows black background in user login section
Status in gnome-shell package in Ubuntu:
New
Bug description:
Unlike my laptop, my desktop, has issues with the lockscreen
background, which disappears and goes black after trying to unlock the
lockscreen only after the login section (after you click or type
something in the screen to put the password)
Didn't happen on Ubuntu 23.04 or 22.04 LTS
Happens even on a fresh 23.10 install.
Wayland session.
Tried MUTTER_DEBUG_KMS_THREAD_TYPE=user but did not make any effect.
After some tests, it looks like it happens only when a double monitor is
used.
The second monitor is not affected.
Changing the primary monitor for the dock didn't make any effect
The monitor having the issue: Gigabyte M27Q 2560x1440 170hz, using
Displayport with FreeSync enabled
Second monitor, not having the issue: Zowie XL2411Z 1080p with DVI input.
There are no other symptoms or useful logs somewhere. The session
works fine overall.
Disabling the gnome extensions didn't make any effect.
Picture attached.
