bug#65183: 29.1; Child frame moving and resizing problems

[陈宇迪]

I tried `(setq x-wait-for-event-timeout 0)' and ran the test function.

It was the same.

By the way, I noticed that (though I believe you have read it),

the GTK doc says "(gdk_window_move_resize) avoids strange visual effects.

i.e. the user may be able to see the window first move, then resize, 

if you don’t use gdk_window_move_resize().". That is exactly what I saw.

As expected.

AFAICT KDE does not have any such problems.

We could try gdk_window_move_resize but we'd have to (1) investigate
whether it works well for child frames and (2) what to do on non-GTK
platforms.

What happens when you change 'x-wait-for-event-timeout' to zero?
