Description Tom Tromey 2005-05-16 06:07:34 UTC 
I'm using the applet here:
http://www.chessgames.com/perl/chessgame?gid=1069669
with gcjappletviewer.
(As of this writing I needed a patch to make this work at all,
see the classpath-patches list.)

When the applet window first comes up, if I move the mouse from
the applet window into another unrelated window, the applet
window will do a full refresh.  If I move the mouse from the applet
window to the desktop, nothing special happens.  (The same thing
happens when moving the mouse from a window into the applet, but
again does not happen when moving from the desktop into the applet.)
After I make a move in the applet, this refresh behavior stops.
Comment 1 Thomas Fitzsimmons 2005-05-25 02:01:15 UTC 
Are you using focus-follows-mouse?  If so, this is a known problem; a change in
a window's active state causes an expose event on the entire window, which
triggers a repaint.  We need to find a way to prevent that expose event in the
gtk peers.
Comment 2 Tom Tromey 2005-05-25 15:17:36 UTC 
Yes, I'm using focus-follows-mouse.
Comment 3 Thomas Fitzsimmons 2005-06-09 22:55:39 UTC 
Fixed on GNU Classpath mainline.
