In my game I have a video that plays over the title screen via a div (pode-div). In order for it to look good and work correctly for what I want, I'm using a low opacity level for the video. It was working well until I exported using node-webkit, and in fact it still works on some of the computers I've tested with. But it seems that on some computers the opacity of the video/div isn't set correctly. Is there a way that I can trouble shoot this. For example make the video only show up if the opacity is able to be adjusted correctly on the computer that the game is playing?
