I have a web start Swing/Java2D application with 2 JNLPs, both effectively the
same, except that one of them sets
<property name="sun.java2d.opengl" value="True"/>
On the test machines that I have available to me (Win XP, Linux, Sun Sparc,
Mac) I have never seen a problem with either of them, until yesterday, on a
Dell M90 with nVidia Quadro FX 2500M, that was running Win XP, sp2, and Java 6
u1. On this machine:
o the JNLP without opengl pipeline started and worked fine, but
o the JNLP with opengl pipeline opened with garbled display.
The application was actually working, because I was able to open a menu item
and see more-or-less expected behaviour, i.e. it opened a dialog window,
however, the dialog window was also garbled.
There didn't seem to be any easy thing I could do to get the display to correct
itself, like window exposure, resizing etc. I tried changing the display
pixel resolution (from the default 1920x1200) to see if that might help, but it
didn't.
But I did find a workaround, by changing the display colour resolution from the
default 32-bit to 16-bit, the web start application window magically corrected
itself, and there were no problems from then on.
Known problem?
Unfortunately, I don't have access to this machine again, as it only became
available to me at a trade show, yesterday.
