Title:
  plymouthd crashed with SIGSEGV in script_obj_deref_direct()

  On machine with motherboard Asus PRIME B350M-A with Ryzen 5 2400G
  using internal vega 11 graphics by DVI interface, after boot there was
  screen full of artefacts instead desktop. It's repeating after every
  cold startup, and some but not every reboot.

  I belief that issue is related to graphic card driver, because it is
  detected as Vega 8 mobile and this could be the issue.
