Emulator

Game Name?

Probably any game, but here are the ones I've tested:

1. Super Smash Bros Melee
2. Mario Party 6
3. Mario Kart Wii (Wiimmfi enabled)

Game ID? (right click the game in the game list, properties, info tab)

Tested:
SSBM: GALE01
Party: GP6E01
MKW: RMCE01 (00010004524d4345)

MD5 Hash? (right click the game in the game list, properties, info tab, MD5 Hash: Compute)

SSBM: 0e63d4223b01d9aba596259dc155a174
Party: 010dece78287bcb8cafdeb15f035127a
MKW: 8ca4870ba72eb79d117af034f52d3db1

What's the problem? Describe what went wrong.

When using Vulcan Driver on MacOS, either some graphics don't load, or they are broken.
Also console: "VideoBackends/Vulkan/VulkanLoader.cpp:331 E[Video]: (CreatePipeline) vkCreateGraphicsPipelines failed: (-3: VK_ERROR_INITIALIZATION_FAILED)"

What steps will reproduce the problem?

MacOS 10.13.6, Dolphin 5.0-9285, Vulcan graphics mode with Synchronous shaders.
Just launch a game like Mario Party 6 or SSBM.

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

Yes. 5.0-9285

Is the issue present in the latest stable version?

N/A (Vulcan not Present)

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.)

5.0-9173 (It provides a message: "Failed to load Vulcan Library." 5.0-9285 does not show that message.

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

I attached 2 screenshots and a fifolog. The screenshots are the fifolog, but from both OpenGL (works) and Vulcan (does not work).

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

MacBook Pro, 13-inch, Mid 2014.
MacOS High Sierra 10.13.6 (17G3025)
2.6 GHz Intel i5
16 GB Ram
Graphics Intel Iris 1536 MB

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

Logs might help, since I was getting: "VideoBackends/Vulkan/VulkanLoader.cpp:331 E[Video]: (CreatePipeline) vkCreateGraphicsPipelines failed: (-3: VK_ERROR_INITIALIZATION_FAILED)"
