Bug Description

Dear Sirs,

actually I'm using Ubuntu Mate 17.10 on a 64 bit machine.

This is the output from "uname -a":

Linux <myhostname> 4.13.0-36-generic #40-Ubuntu SMP Fri Feb 16 20:07:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I found strange behaviour after last grub2 updates, done automatically by using:

"sudo apt-get update"

"sudo apt-get dist-upgrade"

Flashing bootmenu screen with black dots is really annoying (see screenshots).

I also fear side effects.

BIOS version is latest update.

Grub2 is

Package: grub2
Version: 2.02~beta3-4ubuntu7.2

What can I do?

Kind regards

Stefan

This is my config:

Same problem after last grub package update on xubuntu 17.10, using old motherboard without UEFI. Only grub os selection menu is laggy. Text boot and tty's are nice and smooth.
