http://bugs.winehq.org/show_bug.cgi?id=59631 --- Comment #25 from Stian Low <wineryyyyy@gmail.com> --- This log for wine 11.9 (without staging) and GE-Proton10-32 seems likely the cause of swapchain/backbuffers differences with staging which I overlooked previously: 0244:fixme:dcomp:DCompositionCreateDevice2 01794F88, {5f4633fe-1e08-4cb8-8c75-ce24333f5602}, 007FED24. Probably fixed by reverting DCompositionCreateDevice() for staging to match wine-11.8 which always returns E_NOTIMPL: ./wine-staging/patches/dcomp-DCompositionCreateDevice2/0005-dcomp-Add-IDCompositionDevice2-stub.patch Code for wine 11.9 without staging: HRESULT WINAPI DCompositionCreateDevice(IDXGIDevice *dxgi_device, REFIID iid, void **device) { FIXME("%p, %s, %p.\n", dxgi_device, debugstr_guid(iid), device); return E_NOTIMPL; } I will test this single change to wine-staging which probably effectively bypasses most/all of dcomp-DCompositionCreateDevice2 patches which seem to need additional work which is now on my radar in relation to swap effect 0x3 and backbuffer count > 1 merge request. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
