Kubuntu Bionic: graphical slowdown after installing recent updates

[Matt Ruffalo]

Hi Rik-

I updated my system last night, and found bad/choppy graphical
performance again this morning. I don't know whether it's the same
issue, but 'apt full-upgrade' would do the following, and I haven't yet
had the chance to narrow anything down:

"""
root at isomorphic:~# apt full-upgrade
Reading package lists... Done
Building dependency tree      
Reading state information... Done
Calculating upgrade... Done
The following NEW packages will be installed:
  libegl1 libgdbm-compat4 libglvnd0
The following packages have been kept back:
  mp3splt
The following packages will be upgraded:

"""

When I have some time, I'll see which packages are pulling in 'libegl1'
and 'libglvnd0'.

Thank you,
MMR...
