Oh, you said that downgrade was a workaround.

So in that case this sounds like a bug in libgl1-mesa-
dri_19.0.2-1ubuntu1.1~18.04.1_amd64.deb

** Tags added: regression-update

** Also affects: xorg-server (Ubuntu)
   Importance: Undecided
       Status: New

** Changed in: mesa (Ubuntu)
       Status: Incomplete => New

Title:
  Xorg crash on 3d-enabled virgl (Haswell host)

Status in mesa package in Ubuntu:
  New
Status in xorg-server package in Ubuntu:
  New

Bug description:
  I am running a KVM virtual machine with 3D acceleration (virgl). The
  host is Arch Linux, the guest is Ubuntu 18.04. However, recently, the
  session started crashing just after the login. In xorg logs, I see
  this:

  Downgrading libgl1-mesa-dri from 19.0.2-1ubuntu1.1~18.04.1 to
  18.0.0~rc5-1ubuntu1 helps.

  Arch on Arch does not fail this way. Mesa version is 19.1.1-1 there.

  On the host, the GPU is Intel Haswell:

  00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon
  E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller
  [8086:0412] (rev 06)

  The CPU is Intel(R) Core(TM) i7-4770S CPU.
