This module enables support for window-level blurs on a wide range of devices.
After installing, be sure to go to Settings app -> System -> Developer Options -> Enable Allow window-level blurs under the Hardware accelerated rendering subheading.
Just installing this module isn't enough to get blur/glass effects on your system; system UI components need to specifically be programmed to take advantage of them. One way of achieving this is by installing mods like ClearLineage (download via Telegram), or Iconify.
My module is similar to other modules, but includes a late_start service to modify certain system props just after boot to expand compatibility to a wider range of devices (including my Pixel 5) which don't work with just the standard read-only props mods.
The Action button simply re-runs this late_start service and restarts the surfaceflinger to ensure it takes effect.
