Screen/Windows inside Power BI doesn't load properly

Hello everybody, 

I am having a "silly" proble: many windows/screens on Power BI appear like the one bellow. After you tried to use that button (in this case I was trying to get the data from Google Analytics) the Power BI loads the screen in a weird format.

I some cases, like when I am getting data, you just have to try 2 or 3 times until the screens loads normally. 

But in other cases the screens always appears in this weird format, making a lot of procedures impossibile to be done.

 I am not sure if I made myself clear ... 

Regards
