XF 1.4 Twitter and Vine image error

Members on my website post Tweets, or Vine videos, but when pages load it is often cut off and doesn't display properly. It seems to be resolved once the member re-loads the page again, but does anyone know what the root of the problem is here, and how to resolve it?

Here is an example. I am on Chrome:

Tweets and Vines aren't embedded by default, so your best bet is to ask who provided the embed code. It might depend how they're doing it.
