Very strange rendering!

A very strange case: I have just looked at this very strange rendering of my Light-font.
What’s going wrong ??? Thanks for helping!


This is the correct one:

In which app?
Which font file format?
What are your hinting settings?

It’s from Fontshops website, presenting the font!
Font created in GLYPHS. File-format: Opentype with auto-hinting. I have create some manual PS hinting here and there, and also added ghost hints here and there. But that could not be the problem, or …?!
Thank you.

I cannot help you unless I know in which app this is rendered. Please ask the Fontshop people how they are creating this picture.

It looks like there was a vertical offset applied on them. All horizontals are thinned.

Thank you Rainer, I’ll ask asap!
