[Bug 1317137] [NEW] visual glitch of lines repeating after ansi-term run in split window

 

Public bug reported:

1) open emacs with new large text file 'foo'
2) M-x split-window
3) M-x ansi-term in the second half of the window, 
4) invoke 'man man' in the term window half
5) edit a long line or two in the remaining half
6) notice every the line above it is repeated from top to bottom, where the other lines of your file are.

these extra lines persist after other edits are made, but not if the
line they are on is highlighted, or if the line they are on is edited.

C-x 1 clears them.

screenshot blank lines actually have 'urls' under them.
