What steps will reproduce the problem?
1. open a file with vim
2. in a new terminal, open the same file with another vim instance
3. resize your terminal

What is the expected output? What do you see instead?
I expect the text to reformat while the terminal resizes. Instead, the text 
gets garbled and never formats properly again. In some cases, the output 
remains affected after dismissing the prompt, during editing. In either case, 
the problem can sometimes be fixed by resizing the terminal window once again 
while editing.

What version of the product are you using? On what operating system?
