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. -- Summary: strange refresh behavior when moving mouse Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: AWT AssignedTo: fitzsim at redhat dot com ReportedBy: tromey at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org,java-prs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21604
