In Heroes of Newerth, there is massive black corruption over top half of screen
anytime, when you move mouse over some game objects, like buildings. This is
HiZ related and goes away when RADEON_DEBUG=nohiz is set. 
I also found out that it goes away completely when I revert
commit 631c631cbf5b7e84e42a7cfffa1c206d63143370

    r300g: allow HiZ with a 16-bit zbuffer

HoN is free to play, however I can make an apitrace if needed.
