I see, thanks for letting me know!
I'm still very not used to this style, but it's good to know it's not a bug.
My monitor is 4k, 3840x2160p. But I also have a 2nd monitor connected, which is 2560x1440p.
But I think it might have to do with some, quirks with the image generation, or design choice. As in, maybe I'm just not used to those type of horizontally stretched images?
Here are some screenshots, which I've uploaded to Discord. The square is for reference, which looks like a perfect square on my monitor.
The homepage also looks stretched, which I way I thought it may be a design choice.
Example of in game scene.
So yeah, I don't think the upscale caused the issue. But maybe the images are already generated horizontally stretched already? And this is the style?
