Just a thing I've noticed: Screenshots seem to be broken when using custom parameters.

I've been playing Evil Within and the screenshots worked.
Then I've created a new shortcut in Galaxy with a no intro parameter. Galxy integration still works, for example achievements - but F12 does nothing, no more screenshots. Launching the game without those parameters makes F12 work again.

yes if you use a different launcher then its a different game and the Galaxy overlay needs to find it
