MuPDF error: syntax error: cannot find ExtGState resource 'GS0'

Description of the bug

I've been using PyMuPDF==1.20.2 for a while and upgraded to PyMuPDF 1.25.1 today. After running the same old code using the same old files, I saw the error below being printed but not raised. It doesn't stop the process.

MuPDF error: syntax error: cannot find ExtGState resource 'GS0'

I decided to keep downgrading gradually until PyMuPDF==1.23.26. This was when the error disappeared.

How to reproduce the bug

To reproduce the problem, please read the pages of any PDF file, and then use get_pixmap.

page = doc.load_page(p)
pix = page.get_pixmap(dpi=100)
image_bytes = pix.tobytes()

Unfortunately, all files I have contain sensitive medical information with identifiers. That's why I haven't added any files to the issue.

[JorjMcKie]

Well, then there is not much we can do, can we.
There is no doubt that the message is correct, though. All you can do is suppressing its display via pymupdf.TOOLS.mupdf_display_errors(False).

First you claim that "all files show the problem", then you claim that "all files contain sensitive medical information". One of those statements is clearly false.

@robinwatts Maybe I should've said "all files I have show the problem". At the same time, all the files I have are medical PDF files.

@JorjMcKie Thanks! I'll use that.
