That was the general feeling. In that case there are several questions:
1. What should be done when a client is writing to a non-client area?
It is wrong to put it in the client area (the way it is done now).
Your suggested hack works when the string is few pixels above the
client area, but is makes no sense when it is below.
2. Whose responsibility it is to recognize this non-client area writing?
Is it x11drv, GDI32 or USER32 ?
I guess that x11drv since it is the part that knows what managed
and unmanaged is, right?
3. How to detect this kind of non-client area writing in a clean way?
Is there a call to do this?
I guess this one I'd have to dig out of the code and the X11 docs.
