WoW corrupted rendering screenshots

[RADV] Blizzard's World of Warcraft (Wine Staging + DXVK) has a rendering
distortions when MSAA is enabled.

Arch Linux, Mesa-git, but this also happens with any stable version of Mesa.
GPU: AMD Radeon HD7770 with the amdgpu Linux kernel driver.
Freshest Wine (git) + Staging patchset (git) + DXVK (git).
Please tell me if you need more info or any logs and how do I do them.

I attached a few screenshots of this issue:
1) Without any AA enabled, and therefore with proper rendering
2) With MSAAx2
3) With MSAAx4
4) And a few screenshots with MSAAx8.

This issue happens only if MSAA is enabled, but does not happen if any other
types of AA are enabled.
