Multi-Monitor Setups No Longer Display Screensavers after Ventura 13.3.1 update

I'm adding my voice to the chorus of users that have had nothing but trouble with screensavers since updating to 13.3.1. Running a Mac Studio M1 Max with three displays - 27" Samsung curved, 24" 2011-vintage VIZIO television, and 24" Cintiq Pro graphics tablet. Before updating to Ventura 13.3.1, there were no issues whatsoever with displaying screensavers to all displays. After updating, screensavers display randomly on one monitor, or on no monitors at all. This includes both Apple screensavers that pull photos from a designated folder, and with previously-functioning third-party screensaver modules.

I have taken the following steps - uninstalling and reinstalling screensaver modules, restarting after uninstall and reinstall. I have rebooted in Safe Mode and attempted the same. I have logged into another account and attempted the same.

I have not yet uninstalled and reinstalled Ventura from scratch, and I'm reluctant to do so given seeing other people do the same to no avail. This is squarely a mess-up on Apple's end.
