            Bug ID: 104290
           Summary: Multisampling gives corrupt rendering
           Product: Mesa
           Version: 17.3
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium

Noisy output

Repro:
https://github.com/ARM-software/vulkan-sdk/tree/master/samples/multisampling

Checkout, build (cmake -DPLATFORM=wayland/xcb) and run
./samples/multisampling/multisampling

There is some weird noise in the output when rendering with multisampling shown
in screenshot at certain angles.

GPU: RX470.
I'm not sure which versions are affected, but it affects at least:
Name            : vulkan-radeon
Version         : 17.3.0-2
Description     : Radeon's Vulkan mesa driver

as packaged in Arch.
