Nested masking & corner radius specs are broken

[devonnuri]

I want to use ScrollContainer inside of CircularContainer.

But, its masking function is not working at all.

Is there a mistake in my code?

The issue arises if you have masking at a lower level inside the scroll container (ie. you are using corner radius a second time).

This is a known shortcoming of the shader right now. A temporary work-around is to put the ScrollContainer inside a BufferedContainer

We had to workaround this exact issue for the osu! results screen, for reference:
