Scene view won't render any canvasItems.

[Filip Sigda]

I was trying to learn how to use windows and viewports and at some point the sprites, collisionshapes, and canvasItems all stopped rendering.

Without knowing more about the steps that you've did to get into that point, it's hard to point what's wrong.

But judging from your screenshot, those Sprite2D should've been showing. but do you know why your back color isn't grey colored?
