"Failed to submit command buffer" using Vulkan

[Silanda]

As per the title, yesterday I had this problem occur when playing certain stages in Soul Calibur 2 (PAL), so I tried upgrading to the latest dev build in order to see if anything improved. It didn't, it got a lot worse: every PAL game that runs at 60Hz now crashes with this error when switching to 60Hz if anti-aliasing is enabled. If the game is running at 50Hz, it's fine. If AA is turned off, it's fine. NTSC games are also fine as far as I can tell.

Is this an emulator bug, driver bug, other? Does anyone have any suggestions on alleviating the problem other than to disable AA while using Vulkan? FWIW, I'm running a Geforce 1080 with driver version 388.71.

Bisect tool reckons that 5.0-5970 might be responsible, but that can't be right as it happens in 5.0-5968, and that's where I reckon it started. I'm going to assume that the original error I encountered in SC2 might have a different underlying cause.

Sadly, the issue remains with that PR. The problem I had with the same type of crash on Talim's stage may not be unrelated either: it happens on that stage when fighting Talim or Xianghua in arcade mode (I was using Ivy), and does not happen when AA is disabled (I can switch AA on after the game switches to 60Hz in order to avoid the initial crash). It also doesn't happen in practice mode, making it slightly annoying to test. Unlike the crash upon switching to 60Hz, it was happening in build 5907 which I was using before today. I haven't tested to find out how far back the problem goes because of it being awkward to test.
