Chart artifacts using jdk1.5 build 7?

Post by maruchan » Sun Jun 11, 2006 8:43 am

Hi all,

Anyone notice any painting artifacts when using the latest jdk 1.5 build 7? I get a whole bunch of random white pixels on my charts, specifically near plotted values.

I haven't tried the latest release yet, but I'll do that now. What operating system do you see this on?

Looks OK on Ubuntu Linux/AMD64.

Sorry for the late reply

It only seems to be happening on my IBM laptop in windows 2000. I tried it in FreeBSD/i386 on the same laptop and it's fine. But any other JVM installed on this laptop produces the same results. Initially I thought it was a graphics card memory issue... I will investigate it further, sorry if I cause any scare!

It is a real-time chart that is being updated by different threads (via InvokeLater of course). If I move a window over the chart, then it seems to draw fine until a few seconds later and it becomes garbled again. However, I have since tested it on 10 other JVMs including p7 on other machines and I can't reproduce it.
