Title:
  ovmf 0~20191122.bd85bf54-2ubuntu3.4 breaks video resolution selection

Status in edk2 package in Ubuntu:
  Expired
Status in edk2 source package in Focal:
  Expired

Bug description:
  After ovmf version 0~20191122.bd85bf54-2ubuntu3.4 is installed, it is
  no longer possible to change the screen resolution. Regardless of what
  is set in "Device Manager" → "OVMF Platform Configuration" → "Change
  preferred resolution", the framebuffer resolution is blocked at
  640x480.

  This issue is not present with 0~20191122.bd85bf54-2ubuntu3.3 and
  disappears when one downgrades.

  Host configuration:

  * Ubuntu 20.04.5 LTS
  * Linux 5.4.0-137-generic
  * libvirt-daemon-driver-qemu 6.0.0-0ubuntu8.16
