D15496: [effects/cubeslide] Fix "sticky" windows detection on Wayland

zzag added a comment.


  This diff has supposed to replace `!w->isManaged` with `w->isSpecialWindow`. As @davidedmundson said, we work around KDE's code. The desktop switch OSD has to set appropriate window type (see scripts/desktopchangeosd).
  
  > I switch desktop, the OSD remains in the middle. Any notification dialogs stay where they should.
  
  Did you replace `return false` with `return !dontSlideStickyWindows`? I think we won't face problems with notifications, only with the OSD.
