--- Comment #1 from Harald Sitter <sitter at kde.org> ---
If it was the progressbar I think we'd see more reports of this. I have however
seen this temporarily at some point, since it went away on its own after some
updates I am rather content in saying that this is either a bug in the grub
config or grub itself.

Please attach the following files to the bug report
- /boot/grub/grub.cfg
- /boot/grub/grubenv
- /etc/default/grub

Additionally zip up and attach all files in /etc/grub.d (alternatively attach
the files individually but I expect there to be a bunch of them).

Once you are sure you've attached all files please try the following.

On a terminal run `sudo update-grub`, then reboot and see if that fixed the
problem.

If it did not fix the problem delete the following directories and files:
- /boot/grub/themes/breeze/progress_bar/
- /boot/grub/themes/breeze/terminal/
- /boot/grub/themes/breeze/oxygenmono10.pf2
and again `sudo update-grub`, then reboot and see if that fixed the problem.

If it did not fix the problem edit the file /boot/grub/themes/breeze/theme.txt
and find the bit where it says 
> # Show the boot menu
> + boot_menu {
below that insert a new line with this content:
> scrollbar = false
save the file and again `sudo update-grub`, then reboot and see if that fixed
the problem.

If it did not fix the problem edit the same file again and remove the line
again. Towards the end of the file you'll find two "progress_bar {}" blocks.
Remove the bottom one, save the file and again `sudo update-grub`, then reboot
and see if that fixed the problem.

If it did not fix the problem edit the same file again and remove the other
"progress_bar {}" block as well, save, `sudo update-grub`, reboot and see if
that fixed the problem.

If none of the above steps fixed the problem you can restore your theme to the
defaults with the command `sudo apt install --reinstall grub-theme-breeze` and
I'll have to take a closer look at your config.

If one of the steps fixed the problem, please add a comment here. Additionally
restore the default with the command `sudo apt install --reinstall
grub-theme-breeze` followed by `sudo update-grub` and reboot to see if the
problem remains fixed. Please add a comment about this as well.
