Zhiyi Zhang : winex11.drv: Use a global Vulkan instance in X11DRV_D3DKMTOpenAdapterFromLuid().
Module: wine Branch: master Commit: 00eff14f33233a7aa2330d9242e1f3584cc3b4e2 URL: https://source.winehq.org/git/wine.git/?a=commit;h=00eff14f33233a7aa2330d924... Author: Zhiyi Zhang <zzhang(a)codeweavers.com> Date: Wed Jun 29 17:39:30 2022 +0800 winex11.drv: Use a global Vulkan instance in X11DRV_D3DKMTOpenAdapterFromLuid(). This avoids opening multiple Vulkan instances when multiple D3D kernel mode adapters are open. Some tests that leak reference to D3D adapters crash because of out of memory errors before this patch.
