I can not confirm this in older or newer Blender version.

Please click on File > Defaults > Load Factory Settings and check if that will resolve this issue. Just make sure you re-bake particles and mesh.

I think I can see this effect with default cube afrer running quick liquid, but I am not sure if this is bug.

Edit after quich testing It seems that increasing Mesh Upres Factor will "offset" the mesh.
