            Bug ID: 106912
           Summary: radv: 16-bit depth buffer causes artifacts in Shadow
                    Warrior 2
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/radeon
          Assignee: mesa-dev at lists.freedesktop.org

Hello,

Shadow Warrior 2 uses D16_UNORM as a shadow map format, and clearing the depth
buffer in one render pass instance and rendering to it in another results in
parts of the depth buffer getting set to 1.0. The game renders correctly with
RADV_DEBUG=nohiz.

I wasn't able to reproduce this issue outside of DXVK so far, so here's a
Renderdoc capture of the issue (captured on Polaris 10):

  https://mega.nz/#!gfoWFDSC!rb9qsW9H6dGq_gsNvpdhPW82mSkZEy94PX-4Ey6BSTs

The render pass in question starts at EID 19473, which should be bookmarked.
For the capture I used Mesa 18.1.1, but the issue is still present in latest
-git.

Regards
- Philip
