will try to bisect ..

This is really a pain to bisect, there are likely several issues around. However for this one, last good commit is 8ad7c19. Looks like something in the ARB_copy_image series seems to cause things to fail, or maybe UE4 is a user for the extension.

    i965: Add support for ARB_copy_image
    
    This, together with the meta path, provides a complete implemetation of
    ARB_copy_image.
    
    v2: Add a fallback memcpy path for when the texture is too big for the
        blitter
    v3: Properly support copying between two places on the same texture in the
        memcpy fallback
    v4: Properly handle blit between the same two images in the fallback path
    v5: Properly handle blit between the same two compressed images in the
        fallback path
    v6: Fix a typo in a comment

Sorry, that's what bugzilla had when I searched you in the 'Assigned to' field. Will use the new one from now on. Let me know if you need some help with this, I can try to debug as well.

Should be fixed by this series:
