Description

Game Name?

What's the problem? Describe what went wrong.

[On the overview of the world map, you can see a ship that has weird lines between it and its shadow that occurs on D3D12 with MSAA regardless of resolution around the castle, does not happen on D3D11 or with MSAA off (other back ends untested)]

What steps will reproduce the problem?

[0. Set backend to D3D12 and enable MSAA (I used 8x)
1. Create a save file
2. Watch the intro
3. Press A to get the ability to move the camera in the world map
4. Go far right and you will see a castle with a ship flying around it, the ship has strange lines between it and the shadow that occur on D3D12 with MSAA and not D3D11]

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

[5.0-10049]

Is the issue present in the latest stable version?

[Untested]

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

[Likely when D3D12 was added back]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

[i5 7500, GTX 1070, Windows 10]

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

[Anything else here]

MSAA is known to cause issues like this, and behaves differently on different backends, hardware and drivers, so I'm not sure this is really a bug.
