Display of Twitter excerpts - feature or bug? [View all]

I often see tweets that have screen-captured something and embedded it - and it's divided up into 2 or 3 different sections, and magnified by different amounts in the different parts, and made unreadable.

As an example - this is what I see, viewing a tweet directly on the twitter.com website:



Since it happens so often, do they intend it to be like that - an 'edgy' teaser of what was actually screen-captured, that makes you click on it to see if it becomes readable? Or is it just some bug they haven't ironed out in years? I use Windows 7 and Chrome on a laptop, so it's not as if I have an unusual software combination.
