Title:
  spinner theme flickers OEM logo on password entry

Status in cryptsetup package in Ubuntu:
  New
Status in plymouth package in Ubuntu:
  Fix Released

Bug description:
  spinner theme flickers OEM logo on password entry

  With full disk encryption, the OEM logo is removed, password entry is
  shown in its place with a hint "please unlock drive nvme0n1p3"), after
  password entry the input field dissappears, the status message
  "successfully unlocked" jumps down from its place to where the spinner
  is, and OEM logo is painted again.

  As per Windows 10 boot guidelines the OEM logo space is reserved for
  the OEM logo and shouldn't be used for any status messages or input.
  It would be better to always have OEM logo in place, and input field &
  unlocking messages always under the OEM logo where the spinner
  otherwise is.

  This might be a bug in our cryptsetup / initramfs-tools plymouth
  commands which drives the unlocking, rather than the theme.
