SUMMARY KRDC going fullscreen will always place the application on the leftmost screen STEPS TO REPRODUCE Prequisite: Have multiple screens. 1. Start KRDC and have the window on a different screen that the leftmost one. 2. Connect to an RDP client or switch active windowed connection to fullscreen OBSERVED RESULT The RDP window goes fullscreen on the leftmost screen. EXPECTED RESULT The RDP window goes fullscreen on the same screen the window was. (possible Alternative: Screen that best matches the Resolution configured in KRDC's client settings) SOFTWARE/OS VERSIONS Operating System: KDE neon 6.0 KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.0 Graphics Platform: Wayland ADDITIONAL INFORMATION Tested with krdc-window on central screen (1920×1200), which is also set up as primary. Client settings also specify a resolution of 1920×1200. Left screen is 1024×1280.
This issue got worse: after moving it to another screen, the pop-up toolbar is no longer available (24.08.0).
I also experience something like this, though for me it's the left most and top most screen (My monitors are arranged like a tetris Z piece), I'm working around it by using xwayland/xcb by setting QT_QPA_PLATFORM=xcb in the krdc application shortcut (right click on the K menu, not sure what else to call it) and edit application. Not a real fix for it but on xwayland it'll fullscreen on whatever monitor the original application was on for me, which is the behavior i'd expect.
A possibly relevant merge request was started @ https://invent.kde.org/network/krdc/-/merge_requests/171
It would be nice if anyone could test the proposed solution at https://invent.kde.org/network/krdc/-/merge_requests/171 so it gets release in the next version on april
I am able to reproduce this issue on 24.12.1, .2, and .3. I tested the proposed patch, and it resolves this issue, so that KRDC will go fullscreen on the same monitor that the original window was on.
