active shadow is visible underneath inactive shadow on inactive windows

[Artem Gabrielyan]

I have shadows enabled both for active and inactive windows. Both of white colour; active is 16 in radius, inactive is 8. There is a bug in drawing inactive shadow on inactive window, because traces of active shadow are still visible from underbeath the inactive shadow.

how to reproduce:
- open a window (regular window with borders and shadows enabled)
- click outside the window (for example, on desktop)
- the window becomes inactive, its border becomes inactive, inactive shadow is displayed, but traces of active shadow are still visible

Active shadow (or its traces) should not be visible on inactive windows

It doesn't happen all the time. Sometimes inactive window and its shadows are displayed correctly, sometimes shadows are correctly displayed only on a part of inactive window's border, as shown in attached image.
