This is a serious and very annoying issue, but someone found out why this is happening.
Why is nobody taking on this issue when those problems are very common and not new at all? For me every game running through Proton/Wine crashes within half an hour, and native games around 1-2 hours.

And what's the easy solution on Solus? Removing Vulkan?

    HolySoap There's nothing we can fix. I keep us updated to the latest Mesa which has helped significantly over the last year or so. But ultimately, it's up to the Mesa developers to continue improving support for hardware. We also don't support the amdgpu-pro drivers.

      HolySoap It's not a mesa issue maybe - Have you tried AMDVLK? I am running a Vega64 and i haven't any issues - Maybe an amd driver bug?
