To prevent liquid from going through the cup you probably have to fiddle around with the various FlipFluid controls, including making sure the cup mesh is solid enough – increasing resolution may help. There are several controls that you can experiment with, including Particle Jitter, Surface Tension, Sheeting Effects. Consult the FlipFluid documentation, they also have a good tutorial on using some of those settings, I think.
However, if some of the fluid is escaping the cup just from the different stages of the motion blur itself, I do not think there is too much you can do. None of the Subframe controls seem to work – only setting the Motion Samples seems to do anything and even at its max 32 gives very segmented results.
Would be great if the Octane Blender devs could work with the FlipFluid developer to see if this issue could be fixed. The FlipFluids motion blur does work great with Cycles though.
You can also try Blender’s own fluid simulator to see if it will work with Octane motion blur (I have not tried that yet myself).
