OK, so just before resizing the window manually Vim somehow is in a bad
state. It most likely is related to how the Vim window was resized. Do
you know? In case you are not sure you could use:

Yes. As I mentioned before I would resize the window to accommodate for a opening another file in side window.

 

verbose set columns?
verbose set lines?

Hopefully this leads to some Vim script or an autocommand that triggers
the problem. We need this to be able to write a test for it anyway.
Note that you need to start Vim with "--clean" to make sure your local
setup doesn't change what happens.

Regarding starting Vim with "--clean". The "--clean" option was suggested sometime at the start of this thread. It ran with no issues but it also considerably limited my editing capabilities.

Did I answer your query correctly/completely?

Thanks.

Re: Multiple windows get corrupted

As I mentioned in my post that begins with "Everybody FYI" I had just recently discovered that pulling the edge of the window left or right when the garbling happened it made it the problem go away.

But I was hoping to find a fix for my problem so that it doesn't happen; specially when I am pair coding with a colleague. It gets frustrating specially since I couldn't figure out yet a keyboard short cut for pulling side of window left or right.

Well, does that make the problem go away?

Re: Multiple windows get corrupted

Sorry I made a mess with my posting above as I was trying to reply to specific points in your post.

The number of columns and lines has changed. Did the Vim window
actually change size? It would have gotten more than twice as wide.
Or the font has changed to a much smaller one.

Actually that is my doing. I had (as I usually do) start a session with just one window enough to display one file. So the 258 size is a result of my widening the vim window to make room for multiple windows (files). 

You can try resizing it, e.g. by grabbing the left or right size and
dragging it just enough to make the window one character wider or
smaller. Then check if the 'columns' and 'lines' options did change.

I did as you asked and answer is yes columns option did change by just one character increase.
