How to reproduce the bug

f = 'path/oc-for-ocr.pdf'
dpi = 150

import fitz
from PIL import Image

doc = fitz.open(f)
print(doc.layer_ui_configs())  # shows that almost all layers except "Text" are off

pix = doc[0].get_pixmap(matrix=fitz.Matrix(dpi/72, dpi/72))
img =Image.frombytes('RGB', (pix.width, pix.height), pix.samples)

img.show()  # displays image containing all layers info

This is an upstream error. Opening a MuPDF report. Is this a confidential file, or can I simply attach it here?

[PasaOpasen]

@JorjMcKie sorry, it is confidential

is there any way to hotfix the problem? Like removing hidden layers content

pypdfium2 encounters same problem on this doc but pdf2image and python-poppler work well

A similar result from all the browsers: some show Text only, some show also other content.
