181147 - Window resizing is one step behind mouse pointer -- doesn't repaint when mouse pointer stops moving

Status: RESOLVED WORKSFORME

When resizing a window and the mouse pointer stops moving, but before mouseup,
the window size remains one refresh interval behind.  On my G3-266/Radeon, with
window resize refresh at about 1/4 second, I can move the resize widget all the
way across the screen and wait for feedback, but the window doesn't update until
I move the pointer again or mouseup to catch up.

This is different from the way every other cocoa or carbon app behaves, so my
habits don't adjust to this frustrating lack of feedback.

Reproducible: Always

Steps to Reproduce:
1. Click and hold pointer on a window's resize widget.
2. Move mouse pointer across the screen quickly and stop -- window doesn't resize.
3. Move mouse pointer 1 px, or release mouse button -- window resizes.

This may only work on slower machines (very obvious on a G3-266 with Radeon, in
millions or thousands of colours)
Actual Results:  
Window resize doesn't catch up with the mouse pointer when it stops moving.

Expected Results:  
Window should repaint one more time when the mouse pointer stops moving.

Computer: beige Power Macintosh G3 All-In-One/266, 256MB RAM, ATI Radeon video
card, 17" monitor in 1024 x 768 (thousands or millions of colours).

Mac OS X 10.1.5.

This is an OS bug, I think. WFM on 10.2.3.
