Screenrecording

SUMMARY

On Wayland + Virtualbox using VboxSVGA, dragging / dropping a window via the virtual desktop applet to a different (not visible) virtual desktop sometimes causes that the area where the window was is not updated directly. 
When then the mouse is moved across this area, this area becomes updated with the correct content.

Please see the screen recording (zip file), second >17.
( I tried to cut it but KDEnlive produces bigger files for shorter content. :-/ )
