[maemo-developers] [maemo-developers] GDK_EXTENSION_EVENTS - toolbar?

Disabling GDK_POINTER_MOTION_HINT_MASK (using motion masks instead)
fixed my problem, though now there's another issue which i'm trying to
get a handle on. After moving the drawingarea widget around (toggle
fullscreen, move the hpaned, that kind of thing) the "first event" has
wrong coordinates.

like this:
motionnotify on (190, 120)
motionnotify on (190, 120)
(i lift the stylus up,
toggle fullscreen,
hit the drawingarea with the stylus again)
motionnotify on (-7, 241)
buttonpress on (-7, 241)
motionnotify on (80, 300)
motionnotify on (79, 300)

obviously -7, 241 is the wrong coordinate pair. the
buttonpress+motionnotify then leads to a line being drawn. they're not
always negative / out of bounds so there's no sane way to check them.
maybe one could hook widget-repositions and then set a flag to ignore
the next two xevents, but that's not a good solution.
