As i know, when you have blur effect enabled and when you start maximized application (like web browser) the top of the panel should have a white accent. In kde 4.8 it doesnt redraw it correctly. When you start maximized window eventually in the panel theres no white accent, but when you click on e.g. kickoff menu, then the panel redraws itself correctly. Worse, when you click on some applet like kmix, it only redraws the area which kmix popup had.

Reproducible: Always

Steps to Reproduce:
Start maximized window, try to click on e.g kmix or klipper youll see that panel is redrawn

Actual Results:  
The panel wont be correctly redrawn

Expected Results:  
When i open maximized window, the panel should give white accent like it does with kde 4.7 without any redraws.

This problem existed in kde 4.6, but was fixed in kde 4.7, now its back in 4.8.

kwin: fixing some blur bugs

This should fix 2 issues with the blur effect:
- It is now sufficient to have a damaged EXPANDED blurArea to trigger
  an update of the caching texture.
- No glitches in cases where the taskbarthumbnail effect paints a
  thumbnail of a blurred window.
