Licensee wants to take screenshots that are more than the size of the viewport ingame.
However, they are having trouble because the results depend on the size of the viewport.
1. Take a screenshot using HighResShot 1920x1080.
2.Take a screenshot using a very small or large viewport size as well.
Result: different results are obtained
Expect: same results.
