RV570 here, and Lightsmark seems to be the last app with hyper z.

The upper part of the screen is corrupt when hz is enabled.

When RADEON_DEBUG=nozmask is used, the problem almost goes away, there's still some corruption in the upper right corner though.

With RADEON_DEBUG=nohiz I'm only getting the black line you guys described.
