How to prevent screen "flash" on locale change in Jetpack Compose with AppCompatDelegate?

I added an In-app language picker for my Compose App following this article. but everytime I change the language the screen flashes. I guess it is due to configuration changes

I downloaded the sample app out of curiosity and it has the same issue.

Is there a way to prevent these "flashes" or add a nice transition animation? Ideally I would like to just reload the string resources

Here is a gif about the issue
