The commands entered once I was in vim were as discussed here http://vi.stackexchange.com/questions/6452/can-vim-write-incremental-lines-i-e-on-each-line-a-becomes-b-and-1-becomes-2

Hope this is helpful, great work with this by the way 👍

You didn't tell what's strange about it so not sure where to look for a bug... ;)

Sorry you're right, "strange" isn't helpful at all.
At 0:03 when Vim loads, the last chars on each row aren't shown.
Then at 00:09 when Vim indicates to me the pair of square brackets in red, it covers the last two letters of the preceding word.
Then at and just before 00:23 when I select a column of chars, the preceding [g on each row disappear.
Does it appear this way for you?
To be clear, each of the things I mention here are different from what actually happened in my terminal, outside the recording.
I can make a further recording in Kazam or similar or give you more info about my browser etc, if it renders correctly for you.

Cool, what browser are you using?
Having a video showing the "proper" behavior, or a series of screenshots, would be very helpful to analyze the difference in display.

I rewatched the asciicast once again and I don't see what you described.
Can you maybe create a screenshots of your terminal vs asciinema.org for these cases so I can compare? (or videos if it's easier)

Here's a video of how it should look:

And, it's not just Vim:

I tried playing some videos in Chrome (everything renders fine):

Can you check now? I think it should look better now.
