Dear Maintainer,

Today after the daily upgrades on Trixie/Testing I lost two of my monitors on Wayland (I get all 4 on xorg.).

* What led up to the situation?

Today's daily upgrades: https://pastebin.com/RqVX9Bib

* What exactly did you do (or not do) that was effective (or ineffective)?

Loading the previous kernel was ineffective.
Turning off extensions was ineffective.
Logging-in on Gnome on xorg shows all my monitors.

* What was the outcome of this action?

Two of my 4 monitors still dont show on wayland but do on xorg. They are not listed in the>

* What outcome did you expect instead?

I normally have 4 monitors, two per GPU.

I'm sorry that the upgrade has caused you problems, but I think this
is overstating the severity since there is a workaround (use the GNOME
on Xorg session) and you can still use 2 monitors on Wayland.

Could you try reporting this issue upstream?
https://gitlab.gnome.org/GNOME/mutter/-/issues

The Debian GNOME team has limited ability to help with complex mutter issues.

Notably, Debian Testing went straight from GNOME Shell/Mutter 44 to 46
so there is a whole year of code changes in this week's upgrade. And
it's not practical to revert your computer to 44 or 45 now.

Thank you,
Jeremy Bícha
