screenshot of bug in RAGE

The game RAGE starts and runs, but have some quite severe texture problems. See
attached screenshot.  The problem is especially bad when loading new areas.

Settings these options in default.cfg minimizes but doesn't get rid of the bug
fully:

jobs_numThreads 1
vt_maxPPF 128

as suggested in https://store.steampowered.com/news/6464/

This bug looks quite a lot like one that plagued the Windows drivers (ATI
Performance) back when the game was released:

I have seen video of RAGE rendering fine with radeonsi
(https://www.youtube.com/watch?v=OgqgNrN16KM) so I tried jumping back quite a
few Mesa releases* to see if there was a regression somewhere, but AFAICT it is
still there as far back as 11.2.2. 

I'm guessing the bug happened as a change from radeon to amdgpu on the kernel
side?

* Using a hack for Wine to skip the check for a compat profile.

System environment:
-- system architecture: 64-bit
-- Linux distribution: Debian unstable
-- GPU: TONGA
-- Model: Asus Strix R9 285 2GB
-- Display connector: DVI
-- xf86-video-amdgpu: 18.0.1
-- xserver: 1.20.1
-- mesa: 18.2.0~rc4
-- drm: 2.4.93
-- kernel: 4.17
