SharePoint PDF preview not working

We have some PDFs that are not rendering in SharePoint preview windows. Large percent of the text is not visible on the screen. The 'missing' text is actually present in the page source code, but is somehow hidden on the screen (z-order problem?).

The PDF's render fine directly in all browsers, as well as in all PDF editing apps.

We've tried different browsers, different machines, different networks, and in-private/incognito connections. None of this points to a browser specific issue or caching issue.

Has anyone seen this? The issue surfaced about a week and a half ago. We opened a support case with Microsoft but the experience has been bewildering, to say the least.

Did you get any prompt error messages when previewing the PDFs?

No error prompt. Just missing text.

The text is actually in the page source, it's just not visible. Sometimes, it shows briefly on the screen (<1 second), then it disappears.

I tried inspecting the HTML & CSS but do not have the skills to pinpoint the issue.

SharePoint pdf preview is not working for us. hoping we get the fix soon!

You might want to open a Support case with Microsoft. Perhaps it will help prioritize your tenant's infrastructure for the fix.

But I imagine it will come quickly anyway...

I have a support case open. Yesterday, MS Support acknowledged the issue, and said they are targeting the end of September for a fix. They 'archived' the case for the time being.

I provided Support a few PDF's that exhibit the issue. It is only some PDF's. These PDF's are vendor invoices sent to us by various companies. We are seeing the issue invoices from specific vendors. I cannot tell what authoring tool was used to generate the offending PDF's. Regardless, the PDF's work fine outside of SharePoint preview.

So we'll have to wait for MS to fix the issue.

Hi,

any news regarding this? We seem to have similar issue and PDF's are not opening correctly. Same with you, they are open for about 1sec and after that they turn blank. Open in browser works, but is not effective way to handle these documents.

I didn't find any other place or discussion that related to this problem.

PS: I recommend opening your own support case in order to add weight to the issue for Microsoft.

No. I still am assuming 'end of September', as MS Support told me.

Are you seeing this with PDF's your organization generates? I wonder if the issue started with whatever framework SharePoint uses to render previews, or if it istarted with PDF generation tools out there. The issue for us is only with invoices from certain vendors. I do not want to ask them what tools they use. But I'd like to reproduce it.

Ok.

These are PDF's that are made and scanned by ourselves. Strange is that before summer they all opened normally with preview, but during summer (in August) it was noted that they turn blank after second.

FYI, in our end this seems to work now as previously.

Hi @LenCardinalCCSI-5391 ,

Thanks for your feedback. As per my test, I couldn't reproduce this issue on my end. As a workaround, I would suggest you use open > open in browser to preview the PDF file instead of using Preview button. Also, you can maintain collaboration with Microsoft support to troubleshoot this issue.
