Hello, currently I am experiencing the following issue on a 5K Mac running Windows 8 on Parallels Desktop 10.1.4 (28883): When working in Office 2013 in Fullscreen mode it happens that I encounter video problems when scrolling or pulling data from network storages. This only happens in Fullscreen mode. When I reduce the window size to about half the screen resolution everything just works fine. The problem seems to be related to Office only. Anyone had the same issue? Any suggetions? Thanks in advance.
