> I've rebuilt with the dated patch. Thanks. In my previous patch I wrongly rejected a ConfigureNotify because I didn't correctly calculate the expected size of the native frame from the scaled size we requested earlier. Please try again with the attached patch the basic four behaviors of the first frame with and without menu bar and the second frame with and without menu bar. Don't bother about visibility. I meanwhile tried to run GNOME but I upgraded my Debian since the last time I used it and now most of my previous customizations are gone, display resembles that of a cell phone (or maybe Windows 10), many programs I used earlier are not available any more and tracker hogs my hard disk every time I log in. I have no idea how to disable programs that autostart and don't even know how to log off. So I'm afraid that I won't be able to test things there and will have to rely on your tests even in the future. martin
