Question

I am using a sub viewport container and an sub viewport, where I downscale the screen by a factor and then stretch the subviewportcontainer to cerate a pixel effect. But when I play, a strange artifact appears at the bottom of the screen. I am new and can therefor not upload videos, so I have linked to a drive upload of the issue here. I hope any of you have seen this before, if not, thank you for your help regardless

I found the issue, it was a sclaing issue. The way ti works is I devide the fullscreen dimension by the stretch factor and then stretch. The original size was 1152 x 648 and I streched it to 3840 × 2160 (16:9). After changeing the original size to 1920 x 1080 (16:9), the issue was resolved.
