Great work Robert!!!
I added the PPA and performed a sudo apt-get upgrade, and then
rebooted. After booting up natty, the problem with screen corruption in
menus and title bars was gone! For my testing, the DebugFlushBatches

Also of note is the missing slow typing
Thanks for testing, I have been running it in a gnome environment all

Attaching a debdiff containing the fix, full packages are here if anyone
can help out sponsoring them
