I am running Slicer in Arch Linux (gnome and wayland).
When I load an image in slicer, a strange thing happens in gnome: multiple desktops are added to the system.
In gnome there is always a new, fresh and empty desktop available, that is automatically created and added when in the last one appears at least a single window.
In this case, it creates n empty desktops (they can be also 10-20), without a specific reason.
Those desktops are destroyed when slicer is closed.
For me it is not a huge problem, I’m writing just to point it out.
