Description ultr 2010-10-24 14:03:31 UTC

Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

Using window-specific-settings to make the window transparent does not make them use the Blur effect.

Window decoration is blurred, but its content is not.

Reproducible: Always

Steps to Reproduce:
1) enable Blur effect
2) use window-specific-settings set some window class to be always 80% transparent

Actual Results:  
Window decoration is blurred, but its content is not.

Expected Results:  
Window content should have the same blur level as the decoration.

Intended behaviour: blurring everything is not useful and does not make sense. A window has to explicitly specify that it wants to be blurred. Currently we would not be able to blurr everything because it would result in terrible slowdown.

Is there a setting to disable the decoration blurring, then?

No there isn't. But the blurring of Oxygen's background is actually a bug - it 
should not be blurred. Hope to fix it for 4.6
