When I`m tried to change button placement option in "window titlebars -> titlebar buttons" from left to right, gnome-tweaks become unusable, I cant change any other options or press any button in window and window is flicker.
gnome-tweaks -d output:
(gnome-tweaks:3876): Gtk-WARNING **: 18:38:06.947: gtk_widget_size_allocate(): attempt to allocate widget with width -11 and height 17

(gnome-tweaks:3876): Gtk-WARNING **: 18:38:07.218: gtk_widget_size_allocate(): attempt to allocate widget with width -11 and height 17

(gnome-tweaks:3876): Gtk-WARNING **: 18:38:07.218: Negative content width -23 (allocation 1, extents 12x12) while allocating gadget (node label, owner GtkLabel)

It`s going on with any theme (my theme is Yaru-dark) and corrected only when i place buttons on the right in command line.
