Personally I'm not sure if I'm choosing the correct package for the bug.
But this bug is described in following ubuntu forum page:

http://ubuntuforums.org/showthread.php?t=1967619

This suggests that the bug is related to grub choosing a graphical mode
or a font which causes the initial screen to be rendered incorrectly.

I experienced this with both following iso files:
http://releases.ubuntu.com/12.04/ubuntu-12.04-desktop-i386.iso
http://releases.ubuntu.com/12.04/ubuntu-12.04-server-i386.iso

I attempted to install from a USB drive created using "Startup Disk Creator" on ubuntu desktop 10.04.4 LTS
the USB drive is a 4GB "JetFlash TS4GJFV20"

the install was attempted on a Compaq Evo D510 Ultra Slim Desktop
computer (Pentium 4 processor, 768 MB RAM, 40 GB HDD)

As suggested in the same forum the following workaround works:
1. Boot the cmputer with the USB drive
2. When the blank screen with small grey rectangle on lower left appear wait patiently for a few minuets.
3. Press Enter
4. The small rectangle will disappear. Now wait again for a few  minuets patiently.
5. Press Enter again.
6. Wait again for a few  minuets patiently. The text mode installer appears. Installation can proceed normally from here.

** Package changed: xorg (Ubuntu) => grub-installer (Ubuntu)

Title:
  12.04 usb drive boot graphic problems

Status in “grub-installer” package in Ubuntu:
  Confirmed

Bug description:
  I am trying to boot from a USB drive containing 12.04. I created the
  boot disk from 10.04. When I boot from the USB drive instead of seeing
  the boot screen to select boot options (install, run from disc, etc.)
  I see a black screen with a grey square in the lower left corner of my
  screen.

  If I cursor down to where install is and select the install screen
  displays fine.

  If instead I wait out the boot screen and the OS continues to load I
  get a garbled screen filled with neon colored patterns, and nothing
  else is viewable. If I right click or move the mouse around the screen
  there are many changes in the patterns, but still nothing viewable
  except the neon garbled mess. (however I can flip over to terminal and
  it works fine.)

  I also had graphic issues with Natty and Oneiric, so have resorted to
  reinstalling and staying on Lucid. Would really like to find out why
  newer versions of Ubuntu (running Unity, though not sure if that is
  the issue) do not work well on this laptop though, since it is not old
  and is a pretty powerful laptop.

  Dell Inspiron 1720 laptop
  GeForce 840M GS graphics card
  4GB Ram
