http://bugs.winehq.org/show_bug.cgi?id=59634 Wehrwolfmann <wehrwolfmann@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #3 from Wehrwolfmann <wehrwolfmann@gmail.com> --- After further investigation, Esme is correct - GdiEntry13 is used solely as DdQueryDisplaySettingsUniqueness (returning ULONG), not as Direct3DCreate9. I confirmed that WPF rendering works correctly WITHOUT the proposed patch. The initial black window was likely caused by first-run initialization, not by GdiEntry13 returning 0. The WPF source (d3dloader.cpp) shows that D3D9 is loaded independently via LoadLibrary("d3d9.dll") + GetProcAddress("Direct3DCreate9"), and GdiEntry13 is only used for display change tracking. Closing this bug as INVALID. Apologies for the noise. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
