Hello again,
I did a little bit of investigation and noticed some things:
* The bug doesn't happen in a virtual machine, whether it is on Debian
Bookworm, Trixie or Sid
* The bug seems to happen on my machine, regardless of whether it was
on Trixie or Sid
* No changes when changing SDDM config to use x11, x11-user or even
x11-wayland
* Using the maui theme instead of the default debian-breeze theme
didn't change anything
* There is no issue when using a different DE
I have recompiled sddm using the sources from apt, and I was able to
gather a real sddm.log file that I am attaching to this message with the
hope it will help.
It should also be interesting to note that I have an AMD integrated GPU
and that there are few upstream issues which already look like mine:
https://github.com/sddm/sddm/issues/1535
https://github.com/sddm/sddm/issues/2134
(also with interestingly the same CPU and the same warnings about random
number generation)
Hope this helps!
I will continue to search later on if anything can fix this issue, now
that I can also directly patch the source code.
