Public bug reported:

Binary package hint: unity

Running FOSS/3D-nouveau drivers on Natty as of today, xterm fonts are
corrupted horribly on input (not on output).

To reproduce:
- install natty beta 2
- update all packages
- Choose "additional drivers" and "experimental FOSS/3d support"
- reboot.
- open xterm in reverse video mode 'xterm -rv' (so it's white-on-black, the 
true way things should be)
- type into the window, all fonts will be horribly corrupted, almost just plain 
white blocks.  however, typing 'ls' blind, the output of ls is fine. but type 
anything else at the prompt and it works.

This is with an NV50-based video card.  My home machine with a radeon
3450 running the FOSS drivers and unity runs xterm without this issue.

This seems similar to another xterm issue with compiz from maverick
(IIRC).. except it affected the intel driver, iirc.  I'll see if I can
dig up that bug for reference.

** Affects: unity (Ubuntu)
     Importance: Undecided
