Bottom right corner pixel gets inverted in TGA

Recommended Posts

While making textures intended for a game engine I discovered a weird issue: when I export TGA files for some reason their bottom right corner pixel gets inverted. If I export the same image to PNG or JPG there are no issues at all. I'm attaching original .afphoto file as well as TGA and an upscaled PNG file converted from TGA for better view.

To reproduce this bug simply create a project and export it as TGA. You should notice exactly one pixel being inverted in the bottom right corner.

I'm using Affinity Photo

Yes, I have reproduced this by exporting a fill layer using various colours

Odd thing is, the H values from both points add up to either 240 or 600 depending on the original. If I use values of 120 or 300 this doesn't occur
