    gtk: Stop setting GDK_EXPOSURE_MASK on random widgets · d5f17549
    Alexander Larsson authored
    These days exposure happens only on the native windows (generally the
    toplevel window) and is propagated down recursively. The expose event
    is only useful for backwards compat, and in fact, for double buffered
    widgets we totally ignore the event (and non-double buffering breaks
    on wayland).
    So, by not setting the mask we avoid emitting these events and then
    later ignoring them.
    We still keep it on eventbox, fixed and layout as these are used
    in weird ways that want backwards compat.
