(Weston) can't move window using titlebar

• Xubuntu 20.04
• weston 8.0.0
• ristretto 0.10.0

I was using weston to try some xfce apps on wayland and found that ristretto can't be moved around. The weston terminal gives me this warning:

(ristretto:87276): Gdk-CRITICAL **: 18:17:20.122: gdk_wayland_window_set_dbus_pr
operties_libgtk_only: assertion 'GDK_IS_WAYLAND_WINDOW (window)' failed

This doesn't happen with catfish 1.4.3 or mousepad 0.4.3 inside weston
