Vertical line artifacts in Gigapixel AI saved image


I am using Gigapixel AI to enlarge my image, and the image looks fine during preview. However, when I save it, I am getting some vertical lines on one side. This is happening with Low Resolution mode and not Standard mode

The issue is observed with both GPU and CPU.

GigaPixel version: 5.7.3
GPU: RTX 2070
CPU: Intel Core i7 8th Gen
OS: Windows 10
