"Ghost windows" taking overview space in Xorg
It seems like some Gtk apps, like Fractal, have a phase where they reserve the window space, but still take, for some reason of theirs, several seconds to render. While no window is displayed in this time, they show up as an empty, transparent frame in Overview. This is also probably partly a Gtk issue, as space should probably be reserved just after the first rendering has been performed.
