If you set the disassembly expression to "reg:rip" it never loads. (I see you changed from "reg:rip.u64" to "reg:rip" recently but it didn't seem to work before either). Related, I don't know if this is intended but if you open 2 disassembly views the second disassembly view doesn't actually open on the current dissassembly line (rip) instead it just opens on the first line of disassembly. Seems like dv->goto_vaddr is 0 for the second case.
