Secondary are my laptop panel and an extra HDMI connected monitor, both in FHD. xrandr information: Screen 0: minimum 8 x 8, current 6400 x 1440, maximum 32767 x 32767 eDP-1-1 connected 1920x1080+0+0

Committed on 17/02/2023 at 16:43. Pushed by mart into branch 'master'. Better screen removal handling handleScreenRemoved never actually removed any view, as we were comparing the screen id wit hthe screen order length, which is updated only after the signal handler is done. Also, make really sure to remove the desktop view from m_desktopViewForScreen by searching the view itslef and not just by the index of lastscreen.
