hi, under some cases, i must draw out some overlapping section, one option is to use object background filling and opacity. But i have no idea, is there any layer concept similar to photoshop, that is, upper layer will masked out lower layer. But in following worksheet,

https://www.geogebra.org/m/fQmh8vwK

the triangle with red background and 100% opacity can not masked out the background filling hatching.

Is there a bug or something i do not know?
