We checked again on a new Machine also running Windows 8 and the error was
gone, after some checks we determined that the new Machine had some new
Updates for Windows 8 installed. We went to check for Updates on the Surface
and after applying all Updates the Error seems to be gone.
Without any recompilation or further settings just by applying the latest
Win 8 Updates the error is fixed.
Scrolling is smooth now. Same executable no changes, so i guess it was some
bug in the runtime libs after all.
