I will have to iterate several pdf documents and attach different stamps, basically just pdf documents containing an image, to them depending on some condition.
The document I used for stamping works fine. However the second stamp, which is a bit older I think, are having some issues. It seems to introduce these artifacts in each corner. Look at the following example:

I had to cover up some secret stuff in blue. The thing to note here is the 2 lines that has appeared in every corner. These do not appear in my first stamp, only the second. It almost looks some sort of alignment thing.
I have been debugging this for hours. The stamps have the same properties, height, width, etc. The only difference between them is the font. The first stamp uses Verdana:
The second stamp is using Century Old:
However when stepping through with the debugger, all fonts are embedded and accessible so perhaps this is not the culprit here. On my local machine I only have Verdana installed as Century is a paid font from Adobe.
What could introduce these artifacts to my pdf? Is something wrong with my second stamp pdf?
