I am experiencing the same issue! This is really annoying as not only does the window shift upwards but when using eg. a web browser, it seems that the mouse is clicking where the links would have been if the window was maximized properly (ie without the shift upwards) rather than where they are. (in the print screen I have posted you can see that my mouse is thinking that it is pointing at the link although it is actually below it).
