WebGraphics hardware can perform early depth-based culling of fragments before computing their color value (in other words, before running your fragment shader). Consequently, if you utilize any features that would affect that, such as discard, alpha-testing, or manipulating gl_FragDepth the hardware's ability to do that optimization will be compromised since the …
