Description (last modified by jef)

I'm working int he latest version of QGIS and I need to georeference a pdf. Georeferencer opens all .pdf files but some are not visible; they appear white with no image detail.

This does not occur on all .pdf files.

I have tried different QGIS profiles and created a new one (this does not fix the bug) I have tried printing the document to pdf and opening the print (that does not fix the bug) The .pdf file is not layered, has no markups, special features, that I can see (using Foxit) This was going wrong for me on 3.16.7 so I updated to 3.16.11 (this did not fix the bug) I have uninstalled all my third party plugins and tried (this does not fix the bug) Same file opens successfully in 3.10.4 (randomly chose an older version where I knew it worked)

I can open the pdf successfully on an older version of QGIS with an older version of GDAl and that works fine.

Up until now I have been able to take screenshots of the pdf files that have this error and geocode those instead, but I will be trying to geocode some large plans soon and I don't think screenshots will suffice.

I have attached the pdf that I opened in the screenshot examples.

Further information can be found on the QGIS issues (https://github.com/qgis/QGIS/issues/45657) and the GDAL issues (https://github.com/OSGeo/gdal/issues/4701) where I have orginally posted this bug. There is information and analysis there from folks.

I have tried to attach files but they are too large to attach. Please see the QGIS and GDAL posts for the document and screenshots.

Also, apologies if any of the settings (Type, Priority, etc.) are incorrect - first timer here, please feel free to edit.

If you need any further info that I can provide, please do let me know. Many thanks in advance!
