--- Comment #6 from Jose Gómez <ad...@dreamcoder.org> --- Gwenview used to use ~/.config/org.kde.gwenviewrc, but now it uses ~/.config/gwenviewrc (maybe a Gwenview, KDE or Ubuntu change). Anyway, your observation is spot on, and it should help debugging the issue. I have done a couple of tests and when the width and height in that config file match the screen size, that is when decorations disappear. In my case, after being in full screen, the issue appears and the file contains: [MainWindow] Height 1800=1800 Width 3200=3200 Whereas if I change one of the parameters as below, it'll start showing the decorations again. [MainWindow] Height 1800=1799 Width 3200=3200 I just tried to simply make the configuration file read-only, but then I get a warning dialog every time I start the application. -- You are receiving this mail because: You are watching all bug changes.
