             Bug #: 30641
           Summary: wine silently replaces requests for thexture formats
                    not supported by hardware with invalid requests
           Product: Wine
           Version: 1.5.1
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: hramrach at gmail.com
    Classification: Unclassified


When running a d3d application using s3tc on drivers that don't have support
for that texture format wine gives lots of complaints like:

err:d3d_surface:surface_allocate_surface >>>>>>>>>>>>>>>>> GL_INVALID_VALUE
(0x501) from glTexImage2D @ surface.c / 2566
err:d3d_surface:surface_upload_data >>>>>>>>>>>>>>>>> GL_INVALID_ENUM (0x500)
from glTexSubImage2D @ surface.c / 2349

GL trace shows:

37923 glTexImage2D(target = GL_TEXTURE_2D, level = 0, internalformat = GL_ZERO,
width = 64, height = 64, border = 0, format = GL_ZERO, type = GL_ZERO, pixels =
NULL)
37923: warning: glGetError(glTexImage2D) = GL_INVALID_VALUE

This is totally useless and bogus.

1) no message is logged about the application using a format that is not
supported.

2) bogus format is used instead so nobody outside of wine can figure out WTF it
is the application tried to do that did not work.
