Hello,
While testing the new OpenGL rendering pipeline of J2SE 5.0, I noticed
what seems to be a bug, but I'd like to check with people here before
filing a report in the database.
I have a simple JFrame with a JPanel inside (see code below). I've
defined a simple paint(Graphics g) method for this JPanel. It displays
fine. When I decrease the window's size, everything is fine. When I
increase it slightly, it is fine too. But if I maximize it or increase
it significantly w.r.t its previous size, the window's content just
vanishes (after freezing for approx. 1 second). I get a blank JPanel.
This happens only if I set -Dsun.java2d.opengl=true.
Am I missing something (e.g. should I set ro do something special when I
want to use this OpenGL pipeline)?
Configuration :
Windows XP sp2
JRE 1.5.0-b64
Graphics Card : NVidia GeForce FX Go5200 64Mb (bios 4.34.20.42C1) on a
Dell Inspiron 8600 (centrino-based laptop)
Display driver : 6.14.10.4586
Mode : 1680x1050 @ 32bits color depth
Thanks,
Emmanuel
