When Rendering Path, the renderer resizes images to fit the screen's size, leaving empty space around the frames!

EXAMPLE:

This affects the output video as well...

My Monitor's size is 1366x768 and I was trying to render a 2k video!

If you need more info ask and I can give!

Using any third-party mods or exotic graphics drivers?

Based on the image, it looks to be about half the frame in width and height, for 2k aka 1080p that'd be 960x540, not 1366x768. So I don't think this is actually anything to do with your screen size. Looks more like a failed attempt at doing 2x anti-aliasing or something the like.

I turn off antialiasing

2k aka 1080p that'd be 960x540, not 1366x768

2k as in 2560x1440

I'm using a few mods, Mainly Optifine.

If you want to see all the mods, just tell me and I can give (Not today tho...)

P.S. When I set the resolution to 1366x768 it works fine.
