Can't fill the information under the stream pop-up cause of display issues

I can't scroll down to see more

If I go fullscreen it's working
So it's a thing about the size of my page I guess

Actually, after playing a bit more with it, when it is being loaded for the first time, it does not display properly. However, the moment I adjust the size of my screen (does not matter if smaller or bigger) it adjust properly.
