I am not sure what might make a tooltip not display, but while I can get tooltips to appear in the main scene of my project, they won't display in the second scene.
Basically, I have a StarSystem class that inherits TextureButton. The StarSystem class has the following statements in it's constructor.
this.HintTooltip = "HERE";
this.MouseFilter = MouseFilterEnum.Pass;
However, none of the tooltips show up. I have tried setting the mouse filter to different values, but it's always the same.
Multiple StarSystem objects are instantiated and added as elements of a
List<StarSystem> when the program launches, and are displayed when the user goes to the second scene. The root of the scene is a Node2D. The StarSystem objects are all added as children of that scene.
Again, I have no idea what might be causing this, so let me know if you need any more information.
