Description

AVE From UnpackToRgbPlanesAvx2Reduce.txt

When using our tool with SaveAsJpeg in ImageSharp, I got this AVE error (see attached error log) for certain images.
Changing the method to SaveAsPng resolved the issue.

Also for color images with a pixel count not divisible by 8 and less than 3 pixels over, a padded copy is created to avoid JPEG encoding issues as a work-around.

Steps to Reproduce

When I checked individual images with the SaveAsJpeg method using a few commands, this was fine, so at this point I am not sure.

@SunaeK Are you able to create a minimal code sample to replicate the issue? I cannot do much without one.

Update. Actually, I think I can see the issue in the code. PR opened.
