GNOME Shell throws the following warning message: 'St-WARNING **: Too many values for border-radius property.' Was fixed with just remove the last '0' on the 'border-radius' property in the '.tile-preview-left.on-primary' class on both files: gnome-shell.css and gnome-shell-high-contrast.css. https://bugzilla.gnome.org/show_bug.cgi?id=744900
