Enabling Window Blurs with Props

[HeyItsJono]

Hi there, I was wondering if anyone knew how to enable window blurs for a blurred system UI on the Pixel 5? I'm on Android 12L (Magisk latest + LSposed latest) and have used the latest MagiskHide Props Config to set the following custom props as True (1).

persist.sys.sf.disable_blurs
ro.sf.blurs_are_expensive
ro.surface_flinger.supports_background_blur

This makes the Settings -> System -> Developer options -> Hardware accelerated rendering -> Allow window-level blurs toggle appear, but even when toggling it on I get no blurs.

If I run su -c "wm disable-blur", I'm told that blurs are supported and enabled, but still no blurs.
I've tried restarting system UI and killing the surface flinger.
Does anyone have any advice?
