             Bug #: 33062
           Summary: wined3d can't handle surfaces created off-screen in
                    application memory
           Product: Wine
           Version: 1.5.24
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: andy at positality.com
    Classification: Unclassified


Created attachment 43706
  --> http://bugs.winehq.org/attachment.cgi?id=43706
Start of "wine <app.exe>" log

Target application: ICR Touch
Application brief: Commercial EPOS software for Windows x86
Interesting feature: uses DirectX calls for skinned UI generation.

Looking at the attached log you will see the main error:

"wined3d_surface_getdc Not supported on surfaces with application-provided
memory"

This error is from dlls/wined3d/surface.c

I have spoken to the programmers an they state that their program creates
off-screen surfaces by default. However, if the original Create Surface request
fails their program will fall back to storing surfaces in graphics memory.

If wined3d_surface_getdc cannot (or does not yet) support off-screen surfaces
shouldn't the creation code (wined3d_surface_create?) also return an error
(e.g. check for SFLAG_USERPTR.)

Apologies if I've missed something obvious, my knowledge of DirectX is a little
rusty! I did post on the forums first.

Best Regards,

Andy
