urxvt + vim repaint issues

[Jack]

What steps will reproduce the problem?
1. Open a terminal
2. urxvt -e "/bin/bash" -c "vim <path of vim file with 100 lines+>"

What is the expected output? What do you see instead?
The buffer is distorted:
-The bottom half of the text is not visible (black area)
-The lines that are visible are not the correct lines (e.g. line 10 is rendered where line 50 should be), moving the vim cursor to a line repaints that line, but that line only

What window manager are you using?
XMonad 0.10

Please provide any additional information below.
This problem disappears if you add a long enough sleep before opening vim, e.g.:
urxvt -e "/bin/zsh" -c "sleep 1; vim <path of vim file with 100 lines+>"
