Davideuck, did you already try HKLM\Software\OEM\TFLOSettings\EnableScroll?
I hope that the scrolling issue can be fixed soon.
EDIT/UPDATE: I managed to disable the TouchFlo scrolling for File Explorer!
Go to HKLM\Software\OEM\TFLOSettings\TFLOIgnoreAPPs. There is a key namen IgnoreAppYT. Change youtube.exe to fexplore.exe and TouchFlo ignores File Explorer!
I hope that will work with any other application, too!
UPDATE 2: We can exclude any application from TouchFlo and have smooth WM6.5 scrolling!
Just add more Strings to HKLM\Software\OEM\TFLOSettings\TFLOIgnoreAPPs, for example IgnoreAppWP with value wmplayer.exe!
That's a major breakthrough, guys! I'm so f*cking happy
