What's the problem? Describe what went wrong.

The main menu renders incorrectly with Vulkan, with most of the background having a translucent white overlay, except for the bottom right corner. In the game itself, the depth of field's focal point is way too close to the camera, and shadows of non-stationary game objects either have artifacts or render another object's shadow, it likes to cycle through both possibilities now and then.

The game looks fine on other backends, however the Vulkan backend does work fine on Windows with the Crimson drivers (same hardware).

What steps will reproduce the problem?

Start the game with AMDGPU on the Vulkan backend and behold.

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, tested on 5.0-5681.

Is the issue present in the latest stable version?

I'm having trouble building it, and the pre-built on pacman gets a SIGABRT, so sorry, no idea.

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.)

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

The fifo logs are too big to upload, sorry, however the screenshots should sum it up pretty well.

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

CPU: AMD Ryzen 1700
GPU: Sapphire Radeon RX580
Operating System: Arch Linux (with Wayland)
Graphics Driver: AMDGPU 1.4.0 (Mesa 17.2.2)

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

Twilight Princess exhibits the same shadow weirdness, but works fine otherwise. Fiddling with the settings does not seem to affect the behaviour.
