Version: 4.8.0 (using KDE 4.8.0) OS: Linux Among others I have the Fade effect enabled. When a window hidden behind other windows closes, it shows in the front and then immediately fades out. Reproducible: Always Steps to Reproduce: 1. Start some application which opens a window and closes it after a while. Pretty much any application will do - in my case it's a software manager which opens a window showing package database refreshing progress. 2. Switch to another application that covers that window (e.g. a browser). 3. Wait until the covered window closes. Actual Results: The covered window appears in front of the covering window and fades out. Expected Results: The window should not be shown at all. It should close in background. I have a nvidia video card with the latest proprietary drivers. The described behavior has been there for quite a few KDE releases, it's not new to 4.8.
