[DXT3] menu in Tribunal now vanishes (regression?)

Hallo,

with the following 2 patches the menu in "The Elder Scrolls III:
Tribunal Morrowind Expansion Pack" version 1.4.1313 german only shows
white blocks instead of the menuitems as before.

When IDirect3DImpl_CheckDeviceFormat reports that D3DFMT_DXT3 isn't
supported the menuitems will draw correct.

When IDirect3DImpl_CheckDeviceFormat reports that D3DFMT_DXT3 is
supported then white blocks appear instead of the menuitems and
glCompressedTexImage2D returns the error code 0x502 (GL_INVALID_OPERATION).

Using NVIDIA drivers 1.0-4349 and updating to 1.0-4496 doesn't solve
the problem.

Is it the OpenGL implementation which is buggy or the way how wine
uses it?

I have attached a log of "wine -debugmsg +loaddll,+d3d_surface Morrowind.exe".
The binary is a no-cd version, but the original one behaves the same.

Some parts from my config:
,-----
| ...
|
| [Version]
| "Windows" = "win98"
| ;"DOS" = "6.22"
| 
| [x11drv]
| "AllocSystemColors" = "100"

| "UseTakeFocus" = "Y"
| "DXGrab" = "N"
| "DesktopDoubleBuffered" = "Y"
| "TextCP" = "0"
| "Synchronous" = "N"

Will send more details if someone wish.

Can you paste here the output of 'glxinfo' ? If GLX does not support S3TC
texture compression, it should not return that 'D3DFMT_DXT3' is supported
(at least not before adding software decoding code :-) ).

Here is the output of glxinfo and also of xdpyinfo.

Have forgotten to mention the patches, so here they are:

2003-09-02
	* dlls/d3d8/d3d8_main.c, dlls/d3d8/directx.c:
	Jason Edmeades <us(a)the-edmeades.demon.co.uk>
	Use a dummy GL context if one is not available when GetDeviceCaps is
	called.
	Remove the compiler warnings introduced in the last DXTn patch.

2003-08-15
	* dlls/d3d8/d3d8_main.c, dlls/d3d8/d3d8_private.h, dlls/d3d8/device.c,
	  dlls/d3d8/directx.c, dlls/d3d8/utils.c:
	Jason Edmeades <us(a)the-edmeades.demon.co.uk>
	DXT1/3/5 support was broken, but unnoticeable since we also indicated
	it wasn't supported.

The patches themself seem to be okay only that the new if-statement in
IDirect3D8Impl_CheckDeviceFormat should be #ifdef
GL_EXT_texture_compression_s3tc because if it's not defined we don't
have the support as you can see in IDirect3DSurface8Impl_LoadTexture
(surface.c:468). So it will lead to white boxes on a system, when at
compile-time the constant isn't defined and the system says it support
it. But this isn't the case for me because the log show that it
definitly calls glCompressedTexImage2D.
