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.

I'm not "blaming" libdrm in a criticizing way :) It's just that it was the
ONLY
updated package at that time that could have caused the bug to appear since
I
doubt libreoffice could be the one that has an impact (see the previous
attachment
with the upgraded packages that day)... As a developper myself (bare-metal,
kernel,
CLI, QT) for the industry, I'm fully aware that there can be bugs at
several levels.

No in mine, I'm afraid. I tried to do that but apt do not want me to. When
I simulate
the downgrade here is what it gives:
$ cat libdrm2-packages-versions
libdrm-nouveau2=2.4.95-1~18.04.1
libdrm-amdgpu1=2.4.95-1~18.04.1
libdrm2=2.4.95-1~18.04.1
libdrm-intel1=2.4.95-1~18.04.1
libdrm-radeon1=2.4.95-1~18.04.1
libdrm-common=2.4.95-1~18.04.1
$ sudo apt-get -s install $(cat libdrm2-packages-versions)

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
gnuplot : Depends: gnuplot-qt but it is not going to be installed or
gnuplot-x11 but it is not going to be installed or
gnuplot-nox
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by
held packages.
Trying to upgrade them 1 by 1 gives the results found in this post attached
file. I
did not go further in downgrading in the fear of having inconsistencies
between
packages versions.
