In the borderless frame next to this window there should be a
set of tiny narrow blue polygons painted next to the green rectangles.
If rectangle is vertical the corresponding polygon is painted to the right of it,
if rectangle is horizontal the polygon is painted below it.
The length of the polygon should be roughly the same as the length of the
green rectangle next to it. If size is significantly different or any of the
polygons is not painted press "Fail" otherwise press "Pass".
Note: one may consider using screen magnifier to compare sizes.
