There is an obscure (at this point), video display issue that only occurs on an install where grub is configured.
So in other words, in a multiboot -
install A - grub is configured on, issue exists
install B - booted from os-prober entry, issue does not occur
(if grub is reconfigured to install B then it shows issue, install A then is fine.
The difference seems to be the install where grub is configured has this section, the problem is in red.
If I remove the red line & reboot then that install no longer shows the video issue.
So the question is - how to remove that line/option permanently so update-grub does not put back

Code:
if loadfont $font ; then
set gfxmode=auto
load_video
insmod gfxterm
set locale_dir=$prefix/locale
set lang=en_US
insmod gettext
fi
