  Problem with DRI2 and GLX - bionic 18.04

Status in mesa package in Ubuntu:

Bug description:
  I have encountered the problem described below, after some recent
  updates in my Kubuntu. After asking on "Answers" I was requested to
  open a bug, so I'm doing it.

  My problem was, that kwin stopped to show graphical effects. I'm using a 
laptop with Intel graphics - HD5500 
  After some log file search I've found, that probably the cause is shown in 

  Xorg.0.log:[  7073.803] (II) AIGLX: Screen 0 is not DRI2 capable
  Xorg.0.log:[  7073.803] (EE) AIGLX: reverting to software rendering

  After some googling, I have found article below, explaining possible root 
cause. I have used a solution proposed there, and after installing 
libegl-mesa0_18.0.0~rc4-1_amd64.deb and libgbm1_18.0.0~rc4-1_amd64.deb my 
problem disappeared. 

  Link below describes details:


  Here is some output from my OS diag tools:
