WORKAROUND: I found a workaround based on the hints at https://help.ubuntu.com/community/OpenChrome#Problems%20and%20solutions . When I set the virtual size of the display to 1024x768 then the screen is displayed correctly and the mouse cannot leave the visible area so there is no corrupted display of the mouse pointer.
