No such message. And this extension seems to se supported
~~~
trace:d3d:parse_extension_string - "GL_ARB_framebuffer_sRGB".
trace:d3d:parse_extension_string  FOUND: GL_ARB_framebuffer_sRGB support.

About blending I see shaders using them
~~~
trace:d3d_shader:shader_glsl_compile     void main()
trace:d3d_shader:shader_glsl_compile     {
trace:d3d_shader:shader_glsl_compile     float m;
trace:d3d_shader:shader_glsl_compile     vec3 r;
trace:d3d_shader:shader_glsl_compile     vec4 ffp_attrib_position = vs_in0;
trace:d3d_shader:shader_glsl_compile     vec4 ffp_attrib_blendweight = vs_in1;
trace:d3d_shader:shader_glsl_compile     vec3 ffp_attrib_normal = vs_in3;

trace:d3d_shader:shader_glsl_compile     vec4 ec_pos =
vec4(ffp_attrib_position.xyz, 1.0);
trace:d3d_shader:shader_glsl_compile     gl_Position = ffp_projection_matrix *
ec_pos;

I have a version where the bug absent but I don't know which patch is a key.
May be 39057? It influences on log.
