Thank you for the detailed report.
Do you call somewhere setBlurEnabled or setBlurAutoUpdate?

[Mihir3646]

@Dimezis Yes, I am using setBlurEnabled every time to enable or disable runtime.
Like

    private void setUpBlurView() {
        final View decorView = getWindow().getDecorView();
        //Activity's root View. Can also be root View of your layout (preferably)
        final ViewGroup rootView = decorView.findViewById(android.R.id.content);
        //set background, if your root layout doesn't have one
        final Drawable windowBackground = decorView.getBackground();

        binding.blurView.setupWith(rootView)
                .setFrameClearDrawable(windowBackground)
                .setBlurAlgorithm(new RenderScriptBlur(this))
                .setBlurRadius(10);

        binding.blurView.setBlurEnabled(true);
    }

It should be fixed in 1.6.3.
Please let me know in case if this issue persists.

Thank you for a quick solution. Let me try with 1.6.3.
