I'm pretty sure this started with rev 4.0-1192.
Then that means it's a driver bug with integers.
I'll try with older versions then and bring the integer stuff to radeon-devs
If you could try the fifio log in this

Supposedly that is also a Mesa + AMD issue.
A screenshot of what it produces would be awesome, since I don't know how it is supposed to look like beside my output on Nvidia. Which it looks sane to me on my end.
