Hi Michael, I am working on dcomp and dxgi CreateSwapChainForComposition. Please see the attached patches. They are on top of wine 8adc2570. I also included a DXVK patch in case you want to test with DXVK. One game I usually use to test it with is Corgi Warlock (SteamID: 414920). I am currently in the process of upstreaming the patches at https://gitlab.winehq.org/zhiyi/wine/-/commits/bug-23698-react-native. However, it seems like dcomp will be a big pain to upstream. A proper implementation would probably require a dwm.exe and some graphics driver integrations (win32u and etc) as well. So it will take some time to upstream it. They might be added to wine-staging soon. Have fun! Zhiyi On 3/21/26 07:38, Michael Ost via Wine-devel wrote:
Hi,
In the process of supporting third party windows DLLs in wine, I'm coming up against several that are blocked on the FIXME for CreateSwapChainForComposition. Their graphics rendering doesn't work - draws blank white - as a result. Rendering happens via a complex interaction between a number of different calls. So I imagine it would be a heavy lift to implement. But I thought it might be used in gaming apps, so there might be some work going on to implement it.
Any thoughts or news on these APIs? Thanks, /Michael Ost
PS: The unimplemented flow is: - DXGI — creates and presents the swapchain (CreateSwapChainForComposition, Present) - DComp — composites it into the window (CreateTargetForHwnd, SetContent, Commit)
