It was long ago and I'm not sure whether this was patch or simply
transparent background, but it was combination of

https://build.opensuse.org/package/view_file/openSUSE:12.2/grub2/grub2-enable-theme-for-terminal-window.patch?expand=1

https://github.com/openSUSE/branding/commit/ca2953916aa3d06fae71f86ef64ac243277c8178

You can also see why it was dropped in

No :) It is just as mystery to me - I could not find where terminal
window gets displayed. Any pointers are welcome.
