no overlay on anything except minecraft
I can't see the overlay on a game that i want to record, starblast.io. (im using the app). I tried it on minecraft and it worked!
It still doesnt work on starblast.
We've taken a look and found that the app actually uses Chrome internally to display everything, and its difficult to record for some tech reasons.
If you can play the game in the Chrome browser, and turn on the option to record web games, in the 'Web Games' tab in the FBX settings, you should find you can record StarBlast ok.
