PDF's showing with no background in Chrome

I am having some issues with PDF's missing their backgrounds when viewed in Chrome. They seem to work fine on all other browsers. The only thing that has sort of worked is exporting them as PDF/X-3. When viewed in Chrome the background remains but it shows ontop of all images (I will attach a few examples) is there anyway around this? 

 

I have tried flattening before exporting, this hasnt seemed to make a difference. I have also tried to remove transparancy within the background without any improvement. 

 

- HP65 T3 2023 General - This shows correctly on all other browers apart from Chrome, where it removes the background. 

- Hughes-Pumps-HP65-T3 - Background shows in Chrome but images are distorted. 

 

Any advice would be appreciated.

    Chrome is NOT a valid PDF viewer. The only program which can show all PDFs correctly is Adobe Acrobat.

    I just solved this by exporting the background as a PNG and placing it into the file again. The problem was that the vector shape did not show the background in Chrome. The pixel graphic obviously does. Makes the file larger, but at least it works now.

    Sorry, your solution is n solution. PNG knows only alpha ttransparency, more complex transparency models, like blending modes are not supported. The primary solution is to avoid Crome or any other viewer other than Acrobat. The second solution is to export a PDSF with flattened transparency. No need for PNG.

    I understand that. The problem is, this is for a website and we can't control how our users view the PDF. It would be nice if all platforms show one file the same but I guess we don't live in that world. I have made do with the background not showing in chrome.
