Well, it is not actually "failing".
However, look at this ocarina from Thingiverse:
It is quite desirable to have no stringing in the cavity, which is absolutely possible with CURA 2.4 via the "coasting" and z-seam settings. CURA 3.3, however, needs travel moves as indicated in the image.
Another thing is that on layers that consist of two islands (like some layers in the above model) are printed quite efficiently with CURA 2.4 because it basically prints 2 layers on each island before traveling to the other island. CURA 3.3 prints complete layers, which in the case of 2 islands needs twice the travel moves.
Best regards,
Andre

The z-seam options have expanded somewhat in the last few releases - please install a recent Cura and have a play with the various z-seam options. If you still can't get it to do what you would like, please come back with a full description of what you want to achieve and how it's failing. Hope this helps.
