I am using the Oldschool Pixel Shader for my current project. I want to make a 64x64 pixel window, but allow it to be bigger on screen.

So I set the window to 640 x 640, then apply the Oldschool Pixel Shader at 64 x 64.

It works, and each "pixel" is 10 x 10 actual pixels. however it seems to start halfway through a "pixel," so the first "pixel" in each column or row is only 5 x 5 or 5 x 10 pixels.



Is there any way to remove this offset so the full pixel begins in the corner?

That happens on scaled up panels. If that is the case there is nothing you can do but change the drawing system.

I would render the level over a 64x64 bitmap and scale it up by a post process view.

That's a better idea. I ended up making it 650 x 650 and putting a 5 pixel wide frame around it. The game jam allowed for having frames, so that was an easy remedy

Thanks for the info!
