Description Søren Sandmann Pedersen 2005-12-08 07:31:01 UTC 
The program I'll attach demonstrates that calling CompositeUnredirectWindow
on some window will cause existing redirected windows to be sent expose events
and have their backgrounds painted. There is no good reason for this.

Do you still experience this issue with newer soft ?
Please check the status of your issue.
