Maximised fixed window is pushed over to the right? (SOLVED)

[eejit]

I have a 800x600 window with a fixed view:
msg.post("@render:", “use_fixed_fit_projection”, { near = -1, far = 1 })
Which looks fine. (Desktop project)

When I maximize the window, it keeps the ratio (good!) but the displayed portion is pushed all the way over to the right, with a black bar on the left.

I was hoping it would be centered ? So half the black each side ?

Ok - I changed the background image to an actual 800x600 image, and in the main.collection, changed the go object position to be 400, 300.

Now I get this - so I guess that’s the answer
