STEPS TO REPRODUCE 1. Create several desktops 2. Open the desktop grid (meta+g) OBSERVED RESULT The desktops will be displayed horizontally, even though there is plenty of space vertically. It is possible to define the number of lines for the virtual desktops and thus make better use of the screen space, but this will make the pager widget so small that it will be practically impossible to use it (https://i.imgur.com/pKqkvl9.png). EXPECTED RESULT The effect could be to better organize the layout of the desktop areas, making better use of the available space. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.0 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Graphics Platform: Wayland ADDITIONAL INFORMATION Something could be done in the pager widget as well, such as forcing a specific number of lines for it, but as kwin is much more active and well maintained than this widget, I thought it best to report it here.
The desktop grid reflects the number of rows chosen by the user.
