"Synchronize drawing to the vertical blank" Option Missing

I'm running Xubuntu 25.04 and noticed some mild screen tearing issues. The most common solution seems to be going to Window Manager Tweaks and enabling "Synchronize drawing to the vertical blank", but that option doesn't exist for me:

What do I need to do to make that option available?

For reference, here are my inxi -G settings, just in case it helps:

Graphics:

There's no correlative setting in Nivida Settings, either. Also, vblank_mode is set to "auto".

Re: "Synchronize drawing to the vertical blank" Option Missing

Since you have an nvidia driver, have you tried ForceFullCompositionPipeline?

Or alternatively, since it looks like you have 2 video cards, https://forums.developer.nvidia.com/t/v … 1050/58130.
