If I add a fa-time (close) icon to a window head it is not visible. This is with the Material theme.
From Webix 6.0 we have switched to a minified icon package to reduce the library weight. Please, check the list of available icons for Flat/Material themes.
So, you can set the “close” icon as icon:"wxi-close"

For custom icons please follow the related documentation.
The same snippet works well from our side. Could you please clear the cache and double check?
If it doesn’t help, please check with browser dev tools whether any “webixmdi” web font is loaded.
Ok it is working for me now. Thank you!
