Wine issue with hybride amd/nvidia gpu

[pikasoo]

Hi,
Im using wine 8.15 staging with vulkan driver video-hybrid-amd-nvidia-prime on Manjaro (arch linux)

I noticed that if install this driver wine will hang at boot. the process explorer.exe /desktop will high cpu and lock any other activities for wine. killing it will return a windows creation error and will exit wine

this happen with any app, even winecfg

if i remove the nvidia_icd.json file from the vulkan icd.d folder, then wine start fine but is unable to use the discrete nvidia gpu.

I saw a few post about this but usually ended unanswered or closed without solution. I saw a bug report on bugzilla and its status is closed so maybe i got a different issue?
anyway since most were reported back in 2019 i was hoping a solution was found for this issue since...

I would guess that wine try to use the discrete nvidia gpu for rendering windows and other 2d gfx, witch it's unable to do.

Thx for your time

Doing some testing and debugging, this line in the xrandr.c file of the winex11.drv never return for the Nvidia GPU

vr = pvkGetRandROutputDisplayEXT( vk_physical_devices[device_idx], gdi_display,
provider_info->outputs[output_idx], &vk_display );

not sure exactly how to fix this for now. the system has 2 physicals device, first is nvidia second is amd, the amd one work fine. so i don't know if it's a vulkan issue or some extra validation needed in the code there...
