How do I prevent Drawing Canvas from clearing itself?

I have a drawing canvas object the size of my layout. I create sprites, paste them on the canvas, and let them delete by fading out. Everything works fine until the sprites are created near/at the bottom of the screen - then everything gets erased. My window is staying the same size. When there are sprites on the canvas ive tried reszing my window but they did not delete. Just creating at the bottom clears it. Help?

Solution: The layout must stay the same scale (Action > System > Layout > Set layout scale). Once the layout changes scale any following paste (or draw?) actions on the drawing canvas clear it entirely.

Hi Powerwaffle! Do you have any recourses on drawing canvas? I'm still trying to figure ou what it is for..
