950 xl start screen stutters

[Drewstwitts]

Hi. I have the 950 and 950xl both unlocked in the UK and both on insider fast ring with the most up to date firmware and OS. While my 950 is smooth and working really well my 950 xl is terrible on the start screen getting stuck always and won't scroll smoothly then hides tiles for several seconds too. Given the better processor I thought it would run even smoother but it's terrible. Anyone any ideas or had this problem fixed? Andy
