Have you tried this way:

1. Run 'valley'
2. Hit 1 or 2 times 'F4'
3. Move with 'w' (forward), 's' (backward), 'a' (left), 'd' (right) or 
'e' (jump) --- like the legend in the below right corner (you can speed 
up with holding 'shift')

I do NOT see such (huge) corruption on RX580.
LLVM git #7c44c2a308c

@Marek:
R600_DEBUG=noce
do NOT help

Now, I'll try with revert.
Didn't change anything.

But it seems to me that _I_ do NOT see any corruption on RX580 with 
'valley' at all.
When I set it to 'ultra' and anti-aliasing 'x8' (HD resolution) my 
'flickering' texture parts disappear.
It should look like it is.
Have to investigate further...

Cheers,
Dieter
