Why are you using maximum blending? That is not the standard configuration.

Looks fine to me on both Windows and Linux (llvmpipe). Could be a driver bug, but given we don't have this GPU, can't do much about it.

Blending inaccuracies/errors in DX11 are also not bugs. It's a limitation of the renderer.

[Bonney01]

But it has no issues with OpenGL renderer, same GPU, same driver.

PS: I can't find a way to report bugs of DuckStation, so I report a bug to @stenzek here, DuckStation has graphic issues with Metal or Vulkan renderers on macOS Monterey.

[stenzek]

Doesn't mean it's not a driver bug. My A750 corrupts the depth buffer in a similar way in DX12 when zclamp is enabled, so while I checked this dump and zclamp isn't used, doesn't mean it isn't something similar.
