Emulator

What's the problem? Describe what went wrong.

Running Dolphin on Linux with the Mesa 13.0.0 drivers for Vulkan on recent AMD Radeon cards results in a series of errors followed by a segmentation fault when using the Vulkan renderer in Dolphin. The error boxes are in order "Failed to create Vulkan instance", "Fifo shutting down while active", and "Failed to initialize video backend." At this point the game window stays open (fully grey) until the emulator crashes shortly after when interacting with it (including closing it) with the error (sometimes) "terminate called without an active exception", followed by a segmentation fault.

What steps will reproduce the problem?

1. Set the renderer in Dolphin to "Vulkan (experimental)"
2. Launch any game.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?
5.0.r1211, 5.0.r1171

What are your PC specifications? (CPU, GPU, Operating System, more)
OS: Arch Linux 64-bit.
CPU: Intel Core i7 6800k.
GPU: AMD Radeon RX 460 (4 GB version)
Driver: Mesa 13.0 RADV Vulkan Drivers for recent AMD cards/

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I'll admit I'm not sure this is the right place to file the bug given this may just have to do with the early state of the RADV Vulkan drivers (it even prints in the terminal when a program uses them "WARNING: radv is not a conformant vulkan implementation, testing use only."), but they do run VkQuake (the one other Vulkan program I tried) and it does at least seem like a fairly graceless crash. (Plus, if this needs to be filed with Mesa, I'm not sure I know enough to make an especially useful bug report.)
