xscreensaver tearing

I'm using xfce 4.18.2 under Xubuntu 23.04 with Nvidia drivers 525.125.06.  In prior days it used to be sufficient to set these OpenGL environment variables to get tear free OpenGL rendering.

export __GL_SYNC_TO_VBLANK=1
export __GL_SYNC_DISPLAY_DEVICE="DP-1"

For some reason none of the OpenGL xscreensaver modules respect this anymore, or I'm not setting it in the proper place.  I usually start up xscreensaver like this but it's still tearing.

export __GL_SYNC_DISPLAY_DEVICE="DP-1"
export __GL_SYNC_TO_VBLANK=1
xscreensaver -no-splash & disown

If I run glxgears from a terminal I get 60 fps and other OpenGL rendering is also tear free, for example Mame using OpenGL.

Anyone have any ideas about xscreensaver?  This is version 6.02 from the Xubuntu repositories.
