In the game UNIKONG
I have sadly found that the game is partly off my screen so that I can't see the bottom of it (I have tried scrolling down etc, it does work). And though in the beginning levels this is not so much of a problem, in the later ones where the trolls and things are on the levels further down, this does become a problem as I can't see them nor the guy I am playing as. Here is a screenshot:
I am running Ubuntu GNOME 15.10 with GNOME 3.18 and using my browser Firefox 45. I have blocking plugins, but it still didn't work even once I had turned them all off...
$("#unikong-modal").css("top", "0px");
