The editor is probably the Calibre feature I use most often, and I keep Calibre constantly updated. This is the first time I've had this issue. Before Jon suggested I use the other video card I tried uninstalling 4.10.1 and going back to 4.9.1, and the editor opened correctly.
My laptop is an old Lenovo from 2013 with Intel HD Graphics 4000 (the video card which caused the problem). I have to keep it to a driver version that is much older, I assume, than the most recent updates pushed via Windows Update, one that is officially supported by the manufacturer, because the brightness controls stopped working at one point after every update. Hence the problem.
