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.
