    Well Dell released a bunch of drivers today for the 9560. I downloaded the latest Intel 630 driver (same driver version, but A02 now) and my screen flickered while I typed this message. 5 minutes after installation...

    Give DDU a go at removing the old ones to rule out conflicting leftovers?
    What driver version does it give in device manager?

    I've used DDU (in safe mode) to remove my old drivers each time for the past 2 weeks. Have been juggling with each driver version at least twice before Windows forces the OEM drivers. But generic or OEM drivers both seem to flicker, so I don't bother with generics until a new one is out. I'll do group policy method if a new generic does resolve the flicker.

    As for the driver version, I'll check when I get home which is abt 12 hrs from now. But it should be the latest one from Dell. In my case, it's evident if my driver version changes such as a forced update from Windows, since it changes my taskbar width/height back to default and the tray icon returns after I hid it.

    After the initial flicker with the new driver version, I actually didn't flicker for the next 4-5 hrs. I was impressed but I forgot the first rule of Dell: don't get your hopes up. After that, it was back to normal flickering frequency.

    Edit: driver ver 21.20.16.4574, driver date 12/23/16 is the latest oem driver.
