I'm facing a problem with mozilla pdfjs and after reading many github pages I'm here to seek some help.
There are two apps, one is a simple vue app(which I wrote for test), and another enterprise app using angular. In vue app, process of rendering PDF works just fine and scaling works, but in angular app texts are overlapping each other (before and after scale), while both are running on the exact same config (same OS and hardware) and result is same for every different PDF.

rendering result in vue

rendering result in angular

I know it is not a framework related issue, but I cannot figure out what causes this! fonts maybe? or some css properties?

pdfjs version : 2.14.305
