This is the complete set of layout test regressions when blocking WindowServer access:

r=me if this is working as I suggested in my comments.

Is this value already getting set on the WebProcess through a message pass from the UIProcess? I think that was part of your OpenGL fix, right?

> Source/WebCore/platform/graphics/cocoa/IOSurface.mm:304
> +    uint32_t mask = GraphicsContext3D::getOpenGLDisplayMask();

if (uint32_t mask = GraphicsContext3D::getOpenGLDisplayMask())
    CGIOSurfaceContextSetDisplayMask(m_cgContext.get(), mask);
