We have the 992.2 and a Mk8.5 Golf R, both dual clutch and neither behave badly at slow speeds or in stop/start traffic. To be honest the wife has had Golfs in DSG form since the Mk5 and even back then it was good at this but no doubt the later versions are better this.To your point, I spoke with a sales person at Lotus in Beverly Hills and he mentioned that was inherent to the DTC cars but mentioned only one car that did a good job at avoiding this glitch. I think he mentioned Porsche but don't recall for certain.
I reckon it is more a quirk of the Mercedes dual clutch unit than a common behaviour of all dual clutch transmissions and when you do a search this seems to be the case. I think the more you drive it you will learn to adapt your driving style to suit.
