Public bug reported: When clicking on the Settings button in Virtualbox, system freezes instead of opening the Settings window. I see a lot of debug lines on the terminal where I started the gnome-shell ... and by commenting in /usr/share/gnome-shell/js/ui/windowManager.js: the following line: let [success, source, length] = GLib.file_get_contents(global.datadir + '/shaders/dim-window.glsl'); it solves the problem.
Lines on the terminal window: JS ERROR: !!!
