Fixes a rendering issue with steam overlay used in Letterbox projects.
If the overlay does not appear, the issue is with your chromium args or your nw.js version. This plugin cannot fix those issues. Instead, I recommend you look at this thread that lists a lot of common Steam issues:

Also, if you have time, read through the thread, as a lot of people already asked some of the questions you might want to ask.
