But it's no purple fringing with xnview(100quality)

Before this picture is transparent
Its background is purple
Used this software to replace purple to transparent
I think this may be the reason for the purple fringing after conversion.
When there is any compression, webp will appear purple fringing
The difference is that xnview 100quality compression does not appear purple fringing
ImBatch 100quality compression still has purple fringing

Please forgive if it is difficult to understand

Can you please try this "work-in-progress" build? Use"Lossless" option for webp.
Looks like we fixed the problem. Can you confirm?
