[Regression] World of Warcraft causes GPU hang

[Kerrung]

[Regression]
World of Warcraft totally hangs my system with latest DXVK or with 0.52, but works fine with 0.51.
After this hang happens, the only thing I can do is a hard reboot.

Software information

World of Warcraft, highest graphics settings used.

System information

• OS: Arch Linux
• GPU: AMD Radeon HD7770
• Driver: today's latest Mesa-git, but this hang happens with any other Mesa stable version too.
• Wine version: today's latest Wine-git + Staging-git, but this hang happens with any other Wine version too.
• DXVK version: 49bda46 or/and 0.52, no difference, it both lead to hang.

Apitrace file(s)

• I have no idea how to get it.

Log files

• terminal output:
  wow-os-hang-log.txt

• d3d11.log:
  Wow-64_d3d11.log

• dxgi.log:
  Wow-64_dxgi.log

It must be an issue in the driver

@Yardanico

It must be an issue in the driver

I already checked this version. I also tried Mesa 18.0.4 and Mesa 18.1.0, but there's no difference. Hangs happen only if I use the latest DXVK, but do not happen if I use DXVK 0.51.

@Kerrung please bisect to figure out the exact commit that causes the issue. This is critical.

@doitsujin
It seems that I should try to test each commit between 0.51 and 0.52

[doitsujin]

@Kerrung just use git bisect (see here). Please don't forget to recompile before testing each step though... we had that before.

This could be due to game window settings. Can you try with windowed, fullscreen, etc?

Similar logs were with Frostpunk, but without a hang, except on first run. But after setting game window to windowed game worked on radv.

AMD related i guess. Used nVidia 369.24.02 driver, and latest git and do not crash in World of Warcraft atm.

Did not do a lengthy run, so was just popping a few places with my mage.

I can reproduce it with a 580, so its an AMD bug, and it does happen on both trunk and release Mesa.

Window settings don't matter, though I can get to see a few characters, but it will always hang on the loading screen.

@Korvox @Kerrung Please test again with latest master. a0e0ba1 fixes a regression that was causing GPU hangs in Far Cry 3, this issue is probably the same.

[Kerrung]

@doitsujin, iI just tested a0e0ba1 and it fixed for me.
Thank you very much! You are a real code wizard! Thank you for everything you do!
Do you need any more help from me? Unfortunately, I did not have time to do what you asked for.
Is this still relevant and should I still do this?

[doitsujin]

Thanks for reporting back. There's no need to bisect anymore since the issue was fixed.

@doitsujin, I apologize for this offtopic, but I assume that this information can be useful to you. Wine will soon receive the full support of Vulkan 1.1 and, as I suppose in the future Wine will continue to receive all updates of the latest versions of Vulkan.
Can DXVK really benefit from the support of Vulkan 1.1+ in Wine?
Thank you.
