vim + GNU screen + myts 8 scrolling problem

Ive been using my Kindle 3W to share a screen sort of like the Raspberry Pi Display project. Whenever I use vim with the ruler on (:set ruler on), the vim editor leaves remnants on scrolling up or down. I was able to workaround this problem by setting my TERM variable to ansi.

For example:
export TERM=ansi

before launching screen. That seemed to have made the problem go away. I just wanted to share this tip if anybody ran into the same problem.
