用文本编辑器打开 jdev.conf 文件
C:\p5856648_R12_GENERIC\jdevbin\jdev\bin\jdev.conf
找到下面内容
# Disable Direct Draw, on some Windows 2000/XP base computers,
# Direct Draw is cause excessive screen refreshes and slows down drawing.
#AddVMOption -Dsun.java2d.noddraw=true
把最后一行前面的#号去掉！

AddVMOption -Dsun.java2d.noddraw=true
