C Urmm… I hesitate to comment because honestly I’m nowhere close to understanding what this article even means, but fwiw I solved this problem in Ubuntu in single-window mode by holding alt while clicking inside the image window, which allowed me to drag it up and see the bottom. It still wouldn’t let me re-size upward because the toolbox was so tall, so I widened the toolbox until it was two columns, then I could drag the bottom of window upward.
