There is known issue with 7.4, 7.5 and 7.6 where the GPO from AD controller machine coming late to the desktop. It was observed that if loopback policy is applied.
We fixed it in 7.7 but I suggest to use 7.8 which is more stable and has some fixes regarding to memory management issue.
However, due to some issues with windows 10 metro apps, please do not enable "Roam local settings folders" policy as there will be an inconsistency of metro apps when user re-login to the machine. It should be no issue to not sync AppData\Local as this folder is intended to use as temporary folder and can be ignored. It's the same behavior when you use windows roaming profile where it will not synchronize AppData\Local to remote repository.
