Panels sometimes vanish; reopening them causes glitchy behaviour


Recently I noticed that sometimes a panel closes automatically when doing something in particular. When you try to reopen it by right-clicking on the top toolbar and selecting the corresponding panel, it rapidly opens and closes right away. The only workaround is by going to the ‘View’ tab in the top toolbar and open it from there instead.
