D15410: Handle clients which change window metadata during early startup

[Martin Flöser]

graesslin added a comment.


  I just want to point out that such applications are not ICCCM compliant: This property must be present when the window leaves the Withdrawn state and may be changed only while the window is in the Withdrawn state. Window managers may examine the property only when they start up and when the window leaves the Withdrawn state, but there should be no need for a client to change its state dynamically.
  
  KWin doesn't support updates to wm_class and e.g. window rules are broken.
