7 plus' maximized titlebar shows blur only about halfway up the bar, leaving the rest (about .25 inch) totaly perfectly clear at the tip-top all along the top of the bar, with a similer amount of clear area on both sides as well. In other words it's blurred in the middle down to the top of the window and with a border on top and sides of clearness. Sorry, that was not very easy for me to describe, and I don't know how to do screen captures. Question: Is this normal?
