<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Hi all,</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">over the last days we investigated a regression in KWin causing high CPU usage. The problem exists in the combination of any effect animating closing windows and a window being closed before it became visible at all. In such a case the effects would trigger repaints till KWin gets restarted. This strange situation can be triggered by opening Amarok.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Today Philipp finally identified the root cause and fixed it with <span style=" font-size:13px; color:#1f1c1b; background-color:#ffffff;">d07964e0af95911a97c3f474b694570cb279878c [1]</span></p>
