For me - the issue turned out to be related to an NVIDIA BIOS setting. I travel a fair bit so care about battery life and as might be expected when travelling only have the laptop screen as the monitor: so I selected Integrated Graphics. This causes the bad behaviour, in as much that, when I change the BIOS setting to Discrete Graphics - which is faster and I suspect my more desk bound colleagues would choose out of choice - it works just fine.
