This now only seems to happen in the Ranking screen. I was trying to scroll down to see the names by using the scroll bar on my mouse instead of clicking and that's when i encountered this again. If i scroll down the time line pops up with black border and if i scroll to the right i get the above image and the same thing appears below it if going right and down. This happens not with the normal scrolling but when the scroll button is pressed allowed you to scroll in any direction by moving the mouse. (it was working fine then accidentally clicked next thing i know the bug created the above screen.)
