For reproducability, here's what I've been using. (I can reproduce this crash
on both the RADV and AMDVLK Vulkan implementations, and can reproduce it both
on top of sway 1.1 (wayland), and xfce4 (X11)).

* 5.1.3-arch2-1-ARCH
* LLVM 8.0.0
* mesa/vulkan-radeon: 19.0.4
* AMDVLK: (dev branch from nighttime Mountain time 20190602)
* DXVK: winelib version - release 1.2.1

I run "House Flipper" from Steam with DXVK_FILTER_DEVICE_NAME=590.

On 1080p at 60Hz with v-sync, it runs quite well and stable (for hours). If I
disable v-sync and framerate limiting, the crash occurs within a minute
usually.

At 2560x1440 resolution, no refresh rate works in a stable mannner, but I have
tried both 60Hz and 144Hz.

With the game rendering 1080p but scaling up to a 2560x1440 display, I saw it
crash once, but was unable to duplicate it again.

I'm new to low-level development, and would like to help. If I can provide any
information since I can reliably reproduce the issue, I'd love to. Let me know
what would be useful and I'd be happy to get it out to you.

I've also seen the bugs listed in my other comment on the other bug here:
