Report as a bug. The new desktop and rendering seems to have broken a lot and <they also changed figures to be tabbed in a window>(*) that may have fouled up things. Sometimes "new and improved" is only "new and different", not necessarily better (at least until all the issues introduced are resolved).
(*) You might try
f = figure(WindowStyle="normal");
To create a figure window that is independent of other windows, specify the window style as "normal".
Or the other notes go on with
In addition, figures have a larger default size that changes based on the size of your monitor. To use the previous default figure size for a single figure, set its Position property using a position vector of the form [left bottom width height]. Setting the Position property undocks the figure from the figure container.
f = figure(Position=[100 100 560 420]);
To use the previous default initial figure size for all figures, including those in the figure container, set the default figure position of the graphics root object.
set(groot,DefaultFigurePosition=[100 100 560 420])
Whether these will then fix the differences if done in absolute units or not will have to find out by trial and error.
The above can be found by digging through all the links in the release notes from the above top level link.
