F34 Xfce after update - can't recover after suspend or screen lock

I recently updated from Fedora 33 (Xfce) to Fedora 34 (Xfce). In general, a seamless update. However, since the update, recovery after locking the screen or after suspending has been impossible. The reason is that the dialog entry box will not receive focus, so I cannot enter my password. (The buttons respond to clicks, but that is not much help.) Thanks for assistance.

Is it this bug?:
