Public bug reported:
This behavior matters Ubuntu 17.10 (since last upgrade on 2018-03-02,
2.02~beta3-4ubuntu7.2) and Ubuntu 18.04.
A theme is set in /default/grub as
GRUB_THEME=/boot/grub/themes/poly-light/theme.txt. Before this upgrade the
theme-based menu entries were shown normally without overlayed text menu.
The attachment shows the effect: now both kind of menus are shown at the same
time and both menus are selectable at the same time. While selecting one of the
menu entries both menus are flickering ('fight' to be at the top). It is
independent from different themes and screen resolutions.
** Affects: grub2 (Ubuntu)
** Attachment added: "Current grub settings /default/grub"
