jbuilder用了一段时间后，就突然出现屏幕闪烁的很厉害，几乎无法工作了。上次也遇到过，最后重装jbuilder了事，这次胡汉三又回来了，决定google一下是怎么回事，结果在jbuilder网站上发现了
这个：
There are several possible causes for this problem. The most common are related to issues with your graphics driver.
To troubleshoot installation graphics driver issues, try the following:
- First, visit the website of the manufacturer of the graphics card to download and install the latest driver.
- Windows 2000/XP: If the issue is not resolved, try turning down the graphics card acceleration. To do this:
- Right-click on the desktop.
- Choose Properties|Settings|Advanced|Troubleshoot.
- Set the Hardware acceleration to None.
- Start the JBuilder installation program again.
- Try reducing the resolution and/or color depth. Many high-end graphics adapters have high-resolution modes that can cause some aspects of Java to experience difficulties.
- With certain video adapters you may experience some screen painting problems or crashes when running JBuilder. If this happens, try to uncomment a couple of lines in your
/JBuilder/bin/jdk.config file: vmparam -Dsun.java2d.ddoffscreen=false
#vmparam -Dsun.java2d.noddraw
#vmparam -Dsun.java2d.d3d=false
To uncomment the setting, remove the # symbol preceding the lines and try to run JBuilder again to see if the behavior improves.
If this fails to correct the problem, try one of the other troubleshooting suggestions described in the following sections.
