Hello, @lxymahatma

Seems like this will caused by the fact what we missing styles for TitleBar. I'll try to implement it, but i can't guarantee what it will be fast. For now you can use FluentTheme for this. Your App.axaml should be look like this:

<Application.Styles>
  <FluentTheme/>
  <themes:MaterialTheme PrimaryColor="Purple" SecondaryColor="Indigo" />
  ...

So, it will use most of the styles from MaterialTheme, but missing styles should be pulled from FluentTheme and TitleBar should be shown.
