Text Watermark problem

[Aficionado]

Doing some cleanup in all websites with Osclass. I'm using Osclass 3.6.1 with Imagik lib / PHP 7.

I see that the text watermark at the bottom, is not properly showing some letters. The appear "half" like the "g" for example appears without it's "bottom". Like it needs some offset space.

Any ideas ?

Thanks
