What is override accentblur

[Maplespe]

Accent blur is an undocumented API within DWM (Desktop Window Manager). It produces a blur effect similar to Windows 7, but without the full Aero glass styling.

It is typically invoked using the undocumented SetWindowCompositionAttribute API to apply an Accent state to Win32 windows. Many third-party customization tools that restore legacy styles (such as StartAllBack, OpenShell, etc.) rely on these APIs to generate their blur.

Therefore, the "override accent blur" option allows you to replace the effects generated by these APIs with DWMBlurGlass's own effect, effectively overriding the blur applied by those third-party programs.
