It's too late to mention this. But at "788ba754 - win32u: Lookup adapter gpus from their device paths." wine fails to start any GUI apps because gpu->path is not initialized. It's good at the next commit "c67726b3 - win32u: Enumerate devices with a dedicated helper." though.
``` 00ec:err:system:find_gpu_from_path Failed to find gpu with path "PCI\VEN_1002&DEV_73FF&SUBSYS_00000000&REV_00\00000000" 00ec:err:system:update_display_cache Failed to read display config. ```
