Oh I just saw that in clutter 0.8.4 there is:
/* Allow 2-dimensional textures only */
if (gl_target != GL_TEXTURE_2D)
return COGL_INVALID_HANDLE;
whereas in clutter 0.9.2 there is:
/* Allow 2-dimensional or rectangle textures only */
if (gl_target != GL_TEXTURE_2D && gl_target != CGL_TEXTURE_RECTANGLE_ARB)
return COGL_INVALID_HANDLE;
Seems to be since this commit:
http://git.clutter-project.org/cgit.cgi?url=clutter/commit/&id=98035e4d8a418f1f15dfdf56b2883b081a0401b2
it's in 0.8.6
Anyway. I will try to find more newer version than 0.8.4
