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)
