In Mali GPU, FPK will also be disabled, if early-z is disabled?
Hi Mark, Hidden surface removal requires guarantees that the occluder is opaque before fragment shading occurs. Opacity meaning both not using the destination color (not using blending, framebuffer fetch), and with a known sample coverage (either ZS test disabled, so always passes, or a resolved ZS test, so no discards, no alpha-to-coverage).

Hi Peter,
From Mali's spec, I learn that FPK of Mali GPU has a FIFO.But FIFO has limit capacity. will some passed FPK pixels be removed from FPK FIFO? If those pixels will be removed, overdraw is still exist?
