What OS do you use?

It is tested on Windows 10

Could you show the code that you use?

using (var viewer = new Viewer("sample.pptx"))
    var options = HtmlViewOptions.ForEmbeddedResources("p1.html");
    viewer.View(options, 1);

Hi @eugenekr
Thank you for code, also on screenshots: what application do you use for opening PPTX?

No problem, thank you for quick feedback! I’m using Ultra Office.

Checked with version 21.5, the problem is still there.

Hi @eugenekr

I will write in this topic in case of any update.
