SDDM is full white (see attachment), buttons barely visible, but unreadable
after upgrading from
pure Bookworm to pure Trixie. This bug has happened on all over my five other
computers in my household, after following your official Debian upgrading
instructions on your official Debian website.

My previous release is: Bookworm

I am upgrading to: Trixie

Archive date: <Timestamp, available as project/trace/ftp-master.debian.org
     on your mirror or .disk/info on your CD/DVD set> Please, use human
language... You're curious about my original Debian install date? Then it's
2025.07.20. Otherwise, be more specific, and don't talk in hieroglyphs thank
you.

Upgrade date: 2025.08.10
uname -a before upgrade: Warn the users with APT that they should have noted
this for future use.. Only if I would been told this earlier before the
upgrade..
uname -a after upgrade: Linux debian 6.12.38+deb13-amd64 #1 SMP PREEMPT_DYNAMIC
Debian 6.12.38-1 (2025-07-16) x86_64 GNU/Linux
Method: Your official documentation on Your website after Your Trixie release
date...

- Were there any non-Debian packages installed before the upgrade?  If
  so, what were they?
No.

- Was the system pre-update a 'pure' system only containing packages
  from the previous release? If not, which packages were not from that
  release?
Yes.

- Did any packages fail to upgrade?
No.

- Were there any problems with the system after upgrading?
Yes, pulseaudio service fail.


Further Comments/Problems:


Please attach the output of "COLUMNS=200 dpkg -l" (or "env COLUMNS ...",
depending on your shell) from before and after the upgrade so that we
know what packages were installed on your system.

No think I will, its a wall of text and irrelevant.. My machines are pure
Debian, everything is from your repository.
