Shadowphile There's no such thing as "display" in Godot unless you're communicating directly with DisplayServer. There's also no such thing as "stack of images".
You need to be precise with your terminology and use standard Godot terms when describing your setup. Otherwise we cannot know what you're actually talking about. A "display composed of stack of images" could mean different things. Is it a SubViewport with a bunch of TextureRect nodes one on top of another? Or something else entirely?
Best to post your scene structure, your actual code and a video of the unwanted behavior.
If your code/scene is too large, try to isolate the problem into a MRP and post that.
