We use the source property, which inserts an image to decorate the polygon. png is 80 x 80 pixels with a white background (without any alpha/transparency channel).

The solution is that the way we implemented the ToolButton follows the way RelativeLayout is implemented. after of the Stickman class. The instructions in lines 196 to 199 are added after the PopMatrix. Therefore, the context is restored correctly on the PushMatrix. before because they are added after the existents instructions. In other words, if we were to add them in the canvas, the StickMan would be drawn before the translation and scaling. kv files, so we are not presenting them again. The context and vertex instructions are easy to understand.

This is why you can still see the Kivy logo on the background instead of it being all covered by the color. There is another important detail to notice in the previous screenshot. There is a blue line that crosses the first two polygons in front and then crosses behind the last two. This illustrates the fact that the instructions are executed in order and this might bring some unwanted results. In this example we have full control of the order but for more complicated scenarios Kivy provides an alternative.
