There was a problem hiding this comment.
I don’t understand the reasoning behind this change.
If UiConfiguration does not change throughout the application’s lifetime, there is no need to copy it, and we won’t have a thread safety problem.
If UiConfiguration can change, this will result in a stale copy.
