Description

I am using the example code from CreateCheckBox of v2.0.23 to create a PDF with a rendered checkbox (https://github.com/apache/pdfbox/blob/2.0.23/examples/src/main/java/org/apache/pdfbox/examples/interactive/form/CreateCheckBox.java). Regardless of whether I use the original code or change .unCheck() to .check(), the checkmark drawn in the PDF (when the checkbox is checked) is too large and gets clipped (see attached image).

I tried the latest Adobe Reader version and other PDF viewers as well as drawing into a different, pre-existing PDF document. The issue remains. In case it is relevant, I receive the following output when executing the code:
