background of the window instead of trying to paint the background
yourself in the expose_event handler. Below is your sample pro

Do you think is there a way to improve/optimise my code and remove this
problem ?

Of course it does. gtk_box_pack_start() notices the first paramter

But when you let go of the slider, the windows look OK? I don't think
there is any problem then, surely it is understandable that while

Could you explain more precisely what you mean? Do you mean that even
