Same on a Sony Xperia, I thought it was just a pale line, but no it is clearly a little bit of an image. I make it 8 pixels wide on a 1080x1920 image.

Hi all, In my case, I realized this issue caused by turbo-jpeg. If the image's width or height is not evenly divisible by the MCU block size (which is 16 here), the cropping result will create odd-looking strips on the right or bottom edge of the image.

I fix it by adding TJXOPT_TRIM option to discard the partial MCU blocks. Hope this helps.
