This was one of the issues for OpenGLES playground runs on MacOS. OpenGL defaults the depth clear value to 1. But my new depth clipping scheme relies on clearing to 0.
And so not being able to modify the depth clear value meant nothing could draw in subpasses that had a depth attachment.

When depth buffer clipping + StC is enabled, the depth mask toggles very frequently, so we need to make sure it's on before clearing.
We've yet to utilize the stencil mask in the 2D renderer, which is why we haven't noticed this problem up until now.
