Box shadow not work in pdf

[hizebob22]

I can reproduce this with

static void Main(string[] args)
{
Console.WriteLine("Hello World!");
Stopwatch watch = new Stopwatch();
string html = @"<strong>This is a test for converting HTML string to PDF </strong>";
HtmlConverter.PluginPath = "C:\\SpirePDFConvert\\plugins";
Spire.License.LicenseProvider.SetLicenseFileFullPath("C:\\SpirePDFConvert\\license.elic.xml");
using var ms = new MemoryStream();
for (int i = 0; i < 10; i++)
{
watch.Start();
Spire.Pdf.HtmlConverter.Qt.HtmlConverter.Convert(html, ms,false,10 * 1000,PdfPageSize.A4,new PdfMargins(0, 0),Spire.Pdf.HtmlConverter.LoadHtmlType.SourceCode);
watch.Stop();
long total = watch.ElapsedMilliseconds;
watch.Reset();
Console.WriteLine($"{total} ms");
}

}

Hello Bob,

Thanks for your feedback.
I tested your code with the Windows Server 2016 Standard, but did not reproduce your problem. The conversion only cost 4178 ms, 3378 ms.... You mentioned that the Windows Server 2016 Datacenter has no problem, what is the time spent on this server? Here I uploaded my testing demo for your check. Please tell me the time you got while testing my demo. You could test the application several times to see if there's any difference. Looking forward to your feedback.
