Blur does not seem to be working properly. Blur is very subtle for most values. It's not until 50 that anything really happens. Then maybe 80 for the next. But the most significant is between 90 and 91. This occurs for all images and anything that blur applies. Seems like a bug that blur isn't very significant until 91. By then, it's too significant of a difference. 91 is probably appropriate, but the lower values should increase blur more
