Looking further i found that it always "redraw" the screen up on quit from less. I am not sure whether redraw is the exact word to describe it though. BTW any idea how to disable it ?

The work around is to use -X option. I guess -F should imply -X

http://www.greenwoodsoftware.com/less/bugs.html says "The -F option only exits if the entire file can be displayed on one screen."
So it seems that it's desired behaviour.

The -E options is also affected by this bug.

This is not desired behavior. less should exit after displaying the content (i.e. not wait for the user to type 'q').
