In gedit, it looks like attachment #275839 [details]. From bug #729532: > we no longer set an implicit default size of 640x480 on newly created windows, > so they grow to fill the monitor.
Fixed: https://git.gnome.org/browse/gedit/commit/?id=90c742f2e97824878563b4bb4bb926048641dc18 With a quick look there is no other dialogs with the same problem.
