Description RJVB 2015-11-16 14:21:02 UTC 
When a KDE (4) desktop is configured to use the QtCurve kwin theme, Qt5 applications print out the warning

QXcbWindow: Unhandled client message: "_QTCURVE_ACTIVE_WINDOW_"

repeatedly, regardless of whether they use the QtCurve theme or not.

Reproducible: Always

Steps to Reproduce:
1. Configure a KDE desktop to use the QtCurve theme for KWin
2. Start a Qt5 application from a terminal


Actual Results:  
QXcbWindow: Unhandled client message: "_QTCURVE_ACTIVE_WINDOW_"

appears on the terminal repeatedly

Expected Results:  
No such messages

I have not been able to test this with a KF5 desktop.

What is the purpose of the client message, and what would one lose if it is patched out of the code completely?
Comment 1 RJVB 2015-11-16 14:40:55 UTC 
Isn't it a (the) bug that QtCurve doesn't handle the qtc_active_window client message itself, like it does in the GtK2 engine?
