@elextr Now everything works fine, so I can't reproduce the issue, nor with maximized window, nor with not maximized window, and nor with different position of the not maximized window. But the issue was there, and many times it was there, till I started to play around with the window size. I played with the window size only because of the comment of a user in https://github.com/geany/geany/issues/2562#issuecomment-665994757. Next time it will happen, I would like to publish of the treeview_position and geometry from `/tmp/something/session.conf`. The problem: I can't find /tmp/something/session.conf. I find only /tmp/.
