OK, so that sounds more like something to do with Construct. But there's still very little to go on, as ever the reproducible steps are key. Any idea if you can narrow down when precisely the "greying out" (dimmer) appears?
Ashley Another clue is that it does not seem to happen on small projects. I have a project that is about 2000 events and 5000 actions with 8 layouts and 15 event sheets and this is where it seems to happen often.
When I try to reproduce the problem, it doesn't happen, this is why it feels random or something I am doing and not totally aware of... I'm usually quitting the game really fast because I am testing, maybe the game is in the middle of some action or something? But I am using worker so I'm not sure how that effects the Construct tab in Chrome.
Not working on it until tomorrow, I will investigate more then...
