SUMMARY The setting to start Haruna in fullscreen mode has no effect. I have tested in Plasma 6.2.5, in both X11 and Wayland. STEPS TO REPRODUCE 1. Open Settings/General 2. Click the box next to "Start in fullscreen mode" 3. Restart Haruna OBSERVED RESULT Haruna opens in a window. EXPECTED RESULT Haruna opens fullscreen. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux, kernel 6.12.10 KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.1 ADDITIONAL INFORMATION This feature has not worked correctly since it was introduced in Haruna 1.3.0 and was not fixed in 1.3.1 or 1.3.2.
It works only when there is a file to play (opening a file from the file manager, or opening the last played file on startup).
For me it works on Haruna 1.3.2! On Plasma 6.3.0. On Debian 13 (Trixie) - unstable repository. Even though a bit weird with a small quirk: If first opens as a maximized window, so the menu bar is visible and an then it goes into full screen mode. and yes, it opens likes that only when opening a video file. Opening just Haruna by itself, without any video, opens in windowed mode, always. I doesn't seem to remember its maximized state like other KDE programs.
