1) Configure Mediaportal to start up in Window Mode.
2) Select "DefaultWide" as Gui.
3) Start Mediaportal.
4) Look at the top icons. The screen within the window is displaced (about 20 pixels vertical up).
This happens on all machines with Windows 8.1 I tried. In Full Screen Mode everything is ok.
Only solution for me now: Manual resizing of the Window with the mouse and the screen looks normal again.View attachment 139565
