What's the problem? Describe what went wrong.

Dolphin's memory consumption grows unboundedly when running any game with Vulkan backend where after several hours the machine runs out of virtual memory. It's been verified on Mojave. The behavior only occurs with Vulkan/MoltenVK SDK 1.1.97.0 and the latest 1.1.101.0. The memory consumption is normal and holds steady around 600-800MB with games tested when switching out the latest libvulkan.dylib with an older version 1.1.92.1. This behavior is only seen on dev version 5.0-9834 and above.

What steps will reproduce the problem?

1. Download latest dev version of Dolphin (or any version above 5.0-9832).
2. Open Dolphin.
3. Set backend to Vulkan.
4. Run any game.
5. Monitor memory consumption while playing.

NOTE: It's not clear whether this is mac only issue as I don't have a Windows or linux machine available for testing. However, the behavior has been verified by me and one other Dolphin forum member on macOS (Mojave).

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