Nice finding! But I think it is enough to remove this line:
m_layerState.showDebugBorders = true;

Because CoordinatedGraphicsLayer::syncLayerState will set the proper value to the m_layerState.showDebugBorder

Same here.

> Source/WebCore/platform/graphics/texmap/coordinated/CoordinatedGraphicsState.h:79
> +    float debugBorderWidth;

Nowadays, we initialize members like this:
float debugBorderWidth { 0 };

> Source/WebCore/platform/graphics/texmap/coordinated/CoordinatedGraphicsState.h:87
> +};

BTW, do you have any other reason to make a new structure for debug visual?
Even in current implementation, we sent these changes to the compositing thread with a single commit.
