I am creating a simple interface in Glade 3.22.2 and it shows everything as desired except the X button/close button even though 'Deletable' flag is checked in Glade. Using Ubuntu on WSL2 and gtk+ 3.20. When I run glade from my terminal I get these:
GladeUI-Message: 07:40:46.311: 1 missing displayable value for GtkWidget::events
GladeUI-Message: 07:40:46.311: 3 missing displayable value for GtkWidget::AtkObject::accessible-role

WebKitWebView needs an icon named 'widget-webkit2gtk-webview'
WebKitSettings needs an icon named 'widget-webkit2gtk-settings'

(glade:370): Gtk-WARNING **: 07:40:53.398: Error loading theme icon 'dialog-warning' for stock: Icon 'dialog-warning' not present in theme Yaru
How do I fix this?
