Description

Under Xfce 4.14 (Xfwm 4.14) Xorg consumes 100% CPU when Xfmpc window is out of focus. Xorg gets back to normal CPU consumption as soon as Xfmpc window gets focus again. The issue doesn't occur under Fluxbox. It's always reproducible on my 3 boxes running Xfce under Arch Linux.

Version: 0.3.0
