I could reproduce the downgrade issue, libgl1-mesa-dri wanted the newer
libdrm-amdgpu1 but apt failed to tell that in a sensible way.. so
downgrading libgl1-mesa-dri was needed in order to downgrade libdrm
anyway, closing now

So...
You made me question what could have happened if the libraries were not
the cause of KDE's behavior change. You already told me you thought KDE
was involved and indeed it was. The upgrade caused a deactivation of
composition enabling at startup, with a big warning message saying that
it has
In the log "apt-upgrade-libdrm2-no-gnuplot", gnuplot has been entirely
uninstalled :(
As for libgl1-mesa-dri :
$ apt-cache policy libgl1-mesa-dri
libgl1-mesa-dri:
Installed: 19.0.2-1ubuntu1.1~18.04.1
Candidate: 19.0.2-1ubuntu1.1~18.04.1
Version table:
*** 19.0.2-1ubuntu1.1~18.04.1 500
you probably have also upgraded libgl1-mesa-dri from proposed?

You need to remove gnuplot temporarily to test the downgrade, even
though I'm more convinced that it'll not change anything. The X log
shows that DRI2 is set up normally, so it has to do with KDE somehow.

After having gnuplot uninstalled, trying to downgrade libdrm2 is worse
than ever: apt wants to uninstall 3/4 of my desktop environment.

No changes since the initial installation/configuration. It (normally)
defaults to the radeon. radeon module blacklisted. I'll come back later
with results.

No. I noticed it immediately. However, since most of the time fixes come
within
a few days, I did not report the bug at the time, thinking I wasn't the
only one
with that desktop behavior.

It seems apport-collect cannot produce a useful result for now:
dpkg-query: no package matches libdrm
And I couldn't change the affected package to be libdrm2 instead.

Hello.
I upgraded my system on 2019-05-09 and since then desktop effects do not work
anymore. It installed
a new libdrm stack :
$ grep -A 3 "2019-05-09 *08:53:53" /var/log/apt/history.log |
note that there were no changes to the radeon code in the libdrm update,
so blaming the regression on it is weird, I'd suggest to look at KDE
instead

You still have the old libdrm available in the archive btw, does
downgrade do anything?

Timo, indeed I enable several repositories : backports and proposed updates
among them. I like to have a system with as recent softwares as possible (at
home I use debian testing) and see if
everything is ok, report bugs when needed (like "now" ;) for this one. I'm
usually quite impressed

you have proposed enabled for a reason? Looks like the upgrade is
incomplete, libdrm didn't cause your issues but something else, likely
