The issue is one of kind "It was working already but I do not know what is changed". So I need hints what I can check or try to get it working again 
The Cemu emulator requires Vulkan child window rendering that is not implemented yet in wine-vanilla or wine-staging. See https://forum.winehq.org/viewtopic.php?t=35937
For that reason I installed the app-emulation/wine-lutris from ap-overlay
The lutris fork includes patches to get it working.
I installed it on my Laptop and on my GPD gaming device. Both was working.
Last days I tried to play a game again on GPD, but it does not work anymore.
The error is slight different to the wine-staging
| Code: | | 0160:fixme:vulkan:wine_vk_surface_set_offscreen Application requires child window rendering, which is not implemented yet! |
I deleted the ".wine" folder for testing multiple times. Cemu is not installed, so it use the default (empty) wine prefix.
Tried the precompiled wine lutris using games-util/lutris, and imported into steam client to be used with proton. Same issue
On Laptop the Vulkan still does work with app-emulation/wine-lutris
| Code: | | 0120:fixme:vulkan:wine_vk_surface_set_offscreen Redirecting vulkan surface offscreen, expect degraded performance. |
Both devices does have nearly same USE flags and installed software, so I do not have idea for the root cause |
