You can use Preset Manager to make Raycast Target false by default on all new Image and Text components. Did this on all of my projects and now have much less distractions when building my game UI.

On 8:38 you mentioned that "for some reason, when image is not null you can disable raycast target and it works fine."
That's in fact, incorrect. The reason why the normal button works is because it has a text set as a child, and text also has the 'Raycast target' option enabled by default

Nice tip for a main menu or similar.
But be careful, if you disable it e.g. on a pause menu inside your game scene: Players could accidentaly click elements inside the scene "behind" the UI.

why does it take 6 ms to process RaycastAll though, do you have a low end computer?
