I am aware that packages in 'debian backports' may 'lead to some incompatibility risks' but from
what I have been able to understand the problem seems to be due to other packages (it seems
'kwin') not aligned with the updated packages ( see bug 1076729 (1) and 1081941 (2) ).
At the moment I am not able to try solutions such as rebuild KWin or other system packages,
hence my request to the maintainers if it is possible to backport/update the packages in the
bookworm-backports in order to have all aligned and working so that we can update the system
from backports without building or pinning any packages.
Thanks in advance for considering my request.

Hi,
after upgrading libwayland-* packages from backports Plasma desktop failing to
start freezing
the system at login.
Downgrading the packages to the previous version everything goes back to normal.
These are the updated packages:
Upgrade: libwayland-cursor0:amd64 (1.21.0-1, 1.23.0-1~bpo12+1),
libwayland-server0:amd64
(1.21.0-1, 1.23.0-1~bpo12+1), wayland-protocols:amd64 (1.31-1, 1.37-1~bpo12+1),
libwayland-egl1:amd64 (1.21.0-1, 1.23.0-1~bpo12+1), libwayland-bin:amd64
(1.21.0-1,
1.23.0-1~bpo12+1), libwayland-dev:amd64 (1.21.0-1, 1.23.0-1~bpo12+1),
libwayland-client0:amd64
(1.21.0-1, 1.23.0-1~bpo12+1)
Searching for similar problems I found a debian bug (bug=1076729) and this
article that seems to
reproduce the same problems I had:
"A Critical Bug In Libwayland Update Causes Plasma Desktop Freeze On Debian
Sid/Trixie"
https://ostechnix.com/libwayland-update-causes-plasma-desktop-freeze-on-debian/
At the moment I am not able to try solutions such as rebuild KWin or other
system packages.
If the problem also affects other systems, I hope the information can be useful.
While personally I find backporting wayland could be a bad idea, this problem
really
need to be solved by the original Wayland package maintainers: if you have any
idea,
please consider solving it.
Thanks,
Boyuan Yang
