Thank you. I'll try this.
Though at this point I don't understand one part.. In my callback I 
never call gdk_window_get_pointer() nor gdk_event_request_motions(). 
Because of that I would expect that my callback is called only once, the 
first time. Instead of that, it's called basically constantly (but as I 
said I found out some other code than me is calling 
gdk_window_get_pointer() potentially causing that phenomenon).
In your code you don't seem to be skipping some incoming events so I 
would expect the same result as what I'm seeing now?

Is it in fact possible to achieve that I get called only when I say that 
I'm ready? I guess it is...
Anyway, I'll try what you wrote, thank you. But somehow I think it's not 
going to solve my problem. Maybe I'll have to make a small test program 
to understand my problem.
