PDF preview too small

[Benno812]

Hi Sergey,
I tried the new PDF preview feature but when I click on a pdf attachment the popup preview is so small I can't even read the pdf content properly. What's the problem here?

Strange. The popop width should be 1200px.
Do you use 3.3.1 version? Which browser?
And this is for all pdf or only for this one?

This happens with any pdf I upload.
I'm using 3.3.1 and ext 3.3.1.
I tried it on Chrome, Edge and Opera and get the same on all of them.
I've also looked in my CSS to see if I made some changes related to popups width in the past but nothing.
My web developer console give no errors when opening the popup.

If you try on personal demo you will see the same issue?

This issue on PC not mobile, right?

Seems to work fine in the personal demo.
The issue is on PC.
