HTMLToPDFConverter.QtWebKit.Net.Core doesn't always create the Same Document

We are using Syncfusion Version 19.3.0.53 and we are Developing with ASP.NET Core 2.2 on Windows


Sometimes when we create Documents, they don't look the Same. The Fontsize is sometimes smaller than it should be. The Attached Images were Screenshotted at the Same Zoom Ratio. The Documents from which the Screenshots originate were Created right after eachother on the same System without changing anything apart from Reloading. The Document which was too Small was created right after i made some of the Margins smaller and reloaded the View from which we generate the PDF. Then right after that i reloaded the Page again and it was the Right size again. Also We are Converting the PDF from a URL


EDIT: On our local System i got it to work, i found out that the whole page gets distorted to smaller when it has a very long sequence of Underscores "___________". But if we run it on a Windows Azure WebApp the PDF only gets generated with the correct font-size 50% of the Time. The other 50% the font-size is much too small

Hi Chris, 
 
Thank you for contacting Syncfusion support. 

We have tried to reproduce the reported issue with Html URL to PDF conversion, but it is working properly. Syncfusion Html to PDF converter preserves the output PDF document like how the input HTML file/URL is displayed on the WebKit/Chrome based web browsers. Kindly provide more details such as complete input HTML file/URL (with all resources style, fonts, scripts, etc.,), complete code snippet or modified sample, Azure Environment details (OS, bit version, culture settings, RAM size etc.,) , Azure subscription details (app service), target OS, published profile details (Region, Size, hosting plans, etc.,) to replicate the issue in our end. So, that it will be helpful for us to analyse and assist you further on this.   
 
We have attached the sample for your reference, please try the sample on your end and let us know the result. 
Please refer the below documentation link for more information,  
 
Regards,

It seems that i forgot to add the HTML File to the Folder.


The URL is not an open one so it won't be neccessary or useful to you. But the HTML File (The output of the URL you are requesting) is now in the Attachments. This Folder should now contain everything needed
