https://bugs.kde.org/show_bug.cgi?id=259640 Reproducible: Always Steps to Reproduce: "For anyone not being able to reproduce this bug, please try the following method. I've successfully reproduced it in two machines with different distros and kwin settings: (See http://dl.dropbox.com/u/49436584/bug_cube_rotation.avi) 1. Enable the option to show the close window buttons in the Present Windows settings. 2. Have exactly two windows open. 3. Use the Present Windows effect (in the video, I go to the top left corner of the screen). 4. Close one of the windows by clicking on the button that appears on its top right corner. 5. Click on the remaining window. 6. Rotate the cube."
