REVISION SUMMARY
  Patch is based on https://git.reviewboard.kde.org/r/128421/
  This issue - endless repaint loop when a QToolButton is embedded in a KToolBar - causes major battery and performance drain. Just opening an application causes a 15-20% CPU doing nothing. With the patch, CPU usage goes down to 0%.
