Re: [JAVA2D] Resizing a JFrame with OpenGL pipeline

Hi Emmanuel,

I believe this is a known issue; see:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5026186

There are a few bugs in Nvidia's and ATI's drivers that affect our OGL pipeline on Windows that should be resolved over time, as we submit testcases to those driver teams.

Thanks,
Chris

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
