Currently LRZ writes are disabled when depth writes are enabled but the fragment shader is using discard. Additionally, LRZ writes should be disabled when fragment shader is outputting sample coverage or the pipeline state is enabling alpha-to-coverage which behaves as a discard. This fixes rendering problems on Assetto Corsa. Conditions now used for disabling LRZ writes match one set of conditions under which the EARLY_Z_LATE_Z z-test mode is used. It was assumed that in that mode the LRZ writes in binning will not happen until the late-Z phase, but that's apparently not the case.
