Actually you're right, or partially right. I had to stretch mine the full width of the screen to see the scroll bar. Less than that & it doesn't show. For me it's more like 90+ to 95% the total width of the screen. BTW I was scrolled all the way to the right horizontally. I just showed it to be obvious about that in the last frame of the gif. As you can see each frame of the gif, I've resized the width of the program slightly until the vertical scroll bar disappears. Looks like over 90% to me. The blue of the desktop is all that can be seen of the desktop with the left of the program not showing any desktop.
