By default, the Acrylic effect comes with a blur radius of 30, both horizontally and vertically, while not allowing developers or users to modify it. This mod allows the user to modify the default blur radius across all apps that utilize the Acrylic effect, by injecting into DWM and hooking all functions necessary to set the aforementioned blur radius.
This will only work on Windows 10, as Windows 11 seems to have changed the functions that make this implementation work.
In order to use this mod, you must enable Windhawk to inject into system processes in its advanced settings. If you do not do this, it will silently fail to inject. Changing the Windhawk advanced settings will also affect any other mod you have installed, and may cause instability as any other mod that injects into all processes will now inject into system processes too.
This mod will not work on portable versions of Windhawk because DWM is a protected process and can only be modified by a system account. Since the portable version of Windhawk only runs as administrator under your own user account, it will not have the privilege required to inject into DWM.
