The Problem

I found an issue when opening a PDF form in the PDF Viewer.

The PDF is a government administrative form (Castilla y León, Spain) containing interactive form fields (AcroForm).

Current behavior:

• Text appears extremely large.
• Some characters are rendered vertically.
• Form field content is distorted.
• Certain symbols are displayed incorrectly.

Expected behavior:
The PDF should be rendered correctly, as it is in:

• Microsoft Edge
• Stirling PDF Print Preview

The issue appears to affect only the PDF Viewer rendering, since the same document is displayed correctly in Print Preview.

Steps to reproduce:

1. Open the attached PDF.
2. View the document in Stirling PDF.
3. Observe the incorrect rendering of text and form fields.
