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: [email protected]

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
