GUI lags on tree change

In Godot 4.0, having a large tree of Control nodes can result in lag whenever new control nodes are added or removed from the tree. I’m guessing these issues are a result of Godot’s GUI layout functions taking a long time. These issues can be addressed by:

• Reusing controls when possible instead of creating new ones.
  • It appears to be cheaper to have two RichTextLabels that you toggle the visibility on than to change the text on it, so don’t try to reuse the same RichTextLabel for text that changes. ¹
• Use less controls, especially containers, whenever possible.

Other problems

The GUI can lag for a number of other reasons:

• RichTextLabel lags on first draw
