            Bug ID: 109394
           Summary: dark lines visual corruption in ground texture with
                    Heroes of the Storm DXVK
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/radeon
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: tempel.julian at gmail.com
        QA Contact: mesa-dev at lists.freedesktop.org

Originally reported on DXVK tracker:
https://github.com/doitsujin/dxvk/issues/777

Picture showing the corruption:

There are undesired dark lines visible in the ground texture around objects
like bigger buildings.
They are visible with radv and amdvlk (open), but not with amdvlk
(proprietary), and of course neither native DX11 on Windows.

Issue is not new, it probably has always existed or at least for quite some
time now. Happens with LLVM 7/8 and Mesa 18.3/19.

I've created a renderdoc capture which I'm going to upload right now.
