Additional Comments

Printing from the photo tray does not seem to be possible no matter how the printer is configured, but this is easy to work around by using GIMP or another program to print.

Occasional window update errors occur, but this is common on Windows as well.

The window modifier key in Metacity or whichever window manager you use must be turned off or changed to a key other than Alt, otherwise Clone Stamp is useless.

Windows fonts such as Tahoma must be installed in Linux for the text tool to work.

I've used this program under Debian, Arch, and Ubuntu as well with almost no problems and is usable in a productive environment.
