Have you tried building the examples programs in gtkglarea's source
code?  I just did and there's a program called viewlw that displays a
shape that you can rotate by dragging the mouse around.  They capture
the mouse motion events using a normal events mask on the gtkglarea
widget itself and the "motion_notify_event."  It seems to work well.
Maybe you can compare your code to this and see what you are doing
differently.  I looked at examples/viewlw.c.
