Hello @ulhas

I assume that your theme is adding some custom css-styling-rules which leads to this display-behavior. Can you post a link to the specific topic here so that I can have a look?

How exactly is the youtube-link looking which you pasted into the editor? Are you using any extensions for embedding content?

The iframe html-tage has two hardcoded size-values (width: 3840px, height: 2190px) which is definitely not added by the forum. It could be possible that it is caused by the link or another embedding-extension. Otherwise I assume its a theme-related problem – in this case you should contact the developer of your theme.
