another flickering about kivent HOT 2 CLOSED

You should use the GameWorld.system_manager's update_order property to control the order your GameSystem's update in.

In example2.1 you are clock scheduling the entity removal. This means it is entirely possible to render a frame with the new and the old because the Clock schedule means "do NOT remove entity immediately, I don't care if there is a slight delay". You want to directly gameworld.remove_entity

I have pushed some fixes that clean up some internal rendering state, and there is a new Renderer property for your use case 'force_update'. Set force_update to True if you are doing a pattern like this one where you are creating and removing an entity every frame and triggering creation and deletion of batches over and over.

Oh man, it's finally solved (I hope that it's not just temporary random disappear of bug effects). I think that 4f277d7 is cure for my problems.

BTW - I don't need to use force_update , it runs fine with force_update=False.

Thank you.
