[Bug 1752716] [NEW] Weird ascii characters lines all over grub menu

[Bouba]

Public bug reported:

Ubuntu Mate 17.10.1 Artful AMD64
Grub2 2.02~beta3-4ubunut7.2 AMD64

I'm using the 2.02~beta3-4ubuntu7 default version that came from ubuntu
artful/universe amd64 packages

I upgraded to version 2.02~beta3-4ubuntu7.2 from the ubuntu artful-
updates/universe amd64 packages, which triggers flashing ascii
characters lines across the grub menu.

Those ascii characters lines are flashing every seconds, and the pattern
change when i move up and down in the menu.

I had to reinstall Ubuntu Mate 17.10.1 and put everything related to
grub2 (grub-pc / grub-cp-bin / grub-pc-common / grub2-common ) on hold
before doing the post-install repository update.
