3. but then also happens just randomly

What is the expected behavior?
A black box, sometimes square and sometimes with another square over it appears

What went wrong?
I googled if other people have the same problem and found this: https://productforums.google.com/forum/#!topic/chrome/VXoAbUygYdM

Did this work before? N/A

OS Version: 6.2 (Windows 8)

Oh the problem has only happened since google update, so can i un-update, and go back to when google was working properly. why is it, that each update makes chrome worse not better, I thought the point of updates was to fix problems
