If you have problems to boot live systems (from USB), I think it can be solved with mkusb
https://help.ubuntu.com/community/mkusb
because it makes the live system use GFXMODE set to 800x600 except when cloning. So select 'live-only' and in the next menu 'dus-iso2usb' ...
Please report the result here, whatever it is (success or failure), if you try with mkusb.
-o-
But of course, mkusb does not edit /etc/initramfs-tools/initramfs.conf, so that will still be necessary in some computers until this bug is squashed.
