Hi Germano, perfect timing! I wrote patches last few months to improve the multi output behavior in KWin/KWayland and KScreen/libkscreen. Most of them were code cleanup and restructuring code for later improvements. Additionally there is now a new UI and logic for 5.17 coming up. It's already on the beta channel. There is still more to do though. For example on Wayland DPMS off changes have no impact on the overall workspace size. But outputs being off should not be part of overall Screen geometry. Also on Wayland output replication is missing at the moment. In regards to the KCM and its UI changing the ouput replication is still somewhat clunky at the moment in the UI. The KCM is not yet optimized for mobile use case (low priority). The output model should be piped through a proxy model so we can show subsets of disabled or replicated outputs in a clean way. In regards to the bugs you posted: personally I only work on bugs directly related to KWin or KScreen. Applicaiton/Qt bugs someone else need to look into. For bugs not easily being classified as one or the other you can ask me on IRC what kind of bug it is and I try to classify it then. But what bugs you want to concentrate on is independent of that of course. In any case first step would be to get a development setup rolling and build everything from master and for testing back ports the stable branches. KDE Neon Unstable and kdesrc-build is what I use for that because it's simple. For more questions you can also ping me on IRC freenode network: romangg Cheers Roman > > [*] for example: > Screens overlapping after screen unlock > https://bugs.kde.org/show_bug.cgi?id=412368 > > that triggers 404295 > > "show only application on current screen" shows no applications > https://bugs.kde.org/show_bug.cgi?id=404295 > > Panel added to the wrong screen > https://bugs.kde.org/show_bug.cgi?id=408060 > > Plasma on Wayland detects only one screen > https://bugs.kde.org/show_bug.cgi?id=412601 > > Second screen rotated triggers Ark to appear on primary screen exceeding > borders > https://bugs.kde.org/show_bug.cgi?id=412535 > > Second screen rotated triggers Gwenview to appear on primary screen > exceeding borders > https://bugs.kde.org/show_bug.cgi?id=409454 > > Second screen rotated triggers Gwenview to appear on primary screen > exceeding borders > https://bugs.kde.org/show_bug.cgi?id=412536 > > Overlapping screens > https://bugs.kde.org/show_bug.cgi?id=401774
