Description

The ListView widget currently depends on the UWorld's timer manager to fire an event indicating new entries have been generated (see UListViewBase::FinishGeneratingEntry). This can become a problem when adding entries to a list view while the game is paused, as the callback won't fire until the world timer manager resumes. The current workaround is to manually fire UListViewBase::HandleAnnounceGeneratedEntries on the next tick, but we may be able to remove the dependency on the UWorld timer manager by instead subscribing to FCoreDelegates::OnBeginFrame.

Steps to Reproduce
  1. Create a ListView widget and display it on-screen
  2. Pause the game
  3. Add an entry to the ListView, note that it doesn't update until the game is unpaused
