Title:
  Ubuntu 18.04 graphical issue with OVMF

Status in edk2 package in Ubuntu:
  Expired

Bug description:
  Running Ubuntu 18.04 Server virtual machine with UEFI enabled there
  appears to be graphical issues (pixels in wrong place).

  These issues can be temporarily fixed by changing the gfxmode in grub
  config. But from time to time Ubuntu boots into a machine that has
  pixels in wrong place. This problem was originally discovered when
  installing Ubuntu 18 on a xen hypervisor with Secure Boot enabled.

  My suspicion is that its a problem with OVMF and Ubuntu. Issues can
  also be solved by switching to vga=cirrus.
