Title:
  systemd console messages at shutdown corrupted by plymouth

Status in plymouth package in Ubuntu:
  New

Bug description:
  On shutdown, user can escape splash screen and view console logs with the ESC key.
  With the default Ubntu plymouth theme, this breaks rendering of systemd messages, making them unreadable. Other console messages are not affected.

  I will upload a screen shot.

  
  This is reported also here by another user:

  removing splash from the kernel command line options in grub stops the
  problem.

  Also, the standard text theme and the ubuntu-text plymouth theme also avoid the problem.
  This hints there is something wrong with the default theme, perhaps.
