Dualscreen: JOSM take long time for actions

[berndw OSM-Bonn]

System: openSUSE 11.3 64bit, KDE 4.4.95 and earlier. all patches
Nvidia-graphic 8600GT, Driver 256,35, other driver not tested

JOSM since 6 or more weeks ago

every action on my dualsceen/CPU system takes a break up to five seconds with CPU-Load 100 percent on one CPU-Core.

this happens only on the dualscreen, not on a slower Laptop, same OS, 64bit, Nvidia-graphic 8600GT M.

there are no messages, if i start JOSM on a console. What can i do to get more infos???

You could narrow down the change that causes the problems a little (e.g. up to 1 or 2 weeks):

Here are more infos

If i start JOSM with the script (de-version) from Cobra
​http://github.com/cobra/josm-update-script
then there is the problem.
Only one change is made in josm-de.conf
version=latest

If i start it with 'java -jar josm-3387.jar' JOSM works fine

I'll trying to make a new script

Maybe parameter -Dsun.java2d.opengl=true is the problem
