Kwin coredump

After a reboot I noticed an empty (dark) wallpaper on my KDE environment. I tried to right click on the empty desktop to change it to a more colorful one but right click no longer works on my KDE desktop.
It looks like that I'm getting a coredump from kwin.

  journalctl -b -1 -xp3 --no-hostname --no-pager                                                                                                                                                                                                                                                                        jeu. 14 janv. 2021 14:26:27

I believe that I use the default backend that ships with the installation.

I have autologin enabled. Once logged in with the broken desktop I can log out to SDDM and select Plasma (the only option, no -Wayland or -X11) then login again and wallpaper is back as well as right click. If I reboot I go back to the broken desktop.

I changed SDDM theme to Breeze and re-synced settings and this time it worked after reboot. Very strange since I don't recall touching anything related to this lately.

Can you post the last updated packages, before reboot?
How did you update? Which program?
Have you watched the update log for messages?

I use "pamac update" to update my system. I haven't noticed any error while updating.

Today I got a lot of crashes of latte-dock disappearing. Looks like that I'm getting more coredumps from kwin-x11.

Where can I find this list of updated packages? I have a on-demand Timeshift backups so I can check previous system files if needed.

There may be another (or even better) way, but a look at /var/log/pacman.log - starting at the bottom! - will give you what you want. You could use tail on it, but I don't what size would be appropriate. You could grep a date value for that matter - but a look would tell you enough...

Then simple use pamac (gui) history (three dots / menu) you can copy easy there.
