This problem is introduced by WINE 1.3.15 by the commits:

wined3d: Add support for EXT_texture_sRGB_decode.
http://source.winehq.org/git/wine.git/commit/a97c1ad15eb6061cb13888afcbe1090bc2a92784

this commit does not do anything, since it is just declaration of the extension
in Wine3D.

wined3d: Use EXT_texture_sRGB_decode to avoid sRGB texture duplication.
http://source.winehq.org/git/wine.git/commit/75c8e9f7b42173eb3c08e4ae87d485caca431a9b

this commit triggers the problem.

The problem is still present in the current git.

wined3d: Use EXT_texture_sRGB_decode to avoid sRGB texture duplication
commit, utilizes EXT_texture_sRGB_decode extension to avoid texture
duplication.
This extension is supported by Intel Mesa i965 driver. if any other driver not
experiencing this problem then it is Mesa Intel driver's implementation bug.

if I disable this extension via command:
export MESA_EXTENSION_OVERRIDE="-GL_EXT_texture_sRGB_decode"
then everything becomes normal, since WINE is not using this extension.

tested against WINE 1.3.21

if no other drivers experiencing this problem then I will file a bug to
https://bugs.freedesktop.org/, since it is not a WINE problem.

Thank you
