为什么SCIM输入法在FIREFOX下输入文字的时候，CPU占用极高

哈哈，我在浏览器中把JAVASCRIPT和图片载入都关闭了，情况似乎略有好转，占用率没那么高了，而且只在输入的时候才会增高。And only with SCIM.
有趣有趣：）

把图片载入关闭以后，输入框旁边那些闪啊闪的动态表情就没有了，光标放到输入框就不会再CPU占用率升高了。
但是一旦开始用SCIM输入中文的时候，CPU占用率就又上去了，尤其是字词候选条出现在TEXT FIELD以后。
我是菜鸟，也说不太清楚，个人感觉是不是和GTK什么的有关呢？

感觉系统重新刷新屏幕特别费力。
BTW，我什么桌面特效都没开。

如果你装了xgl，并且进入了xgl会话，但没有打开composite，那么就会出现这种情况。

会不会是GTK的问题?

我在xorg.conf中似乎已经打开了Composite了啊。
是这段代码吗？

代码： 全选

Section "Extensions"
    Option "Composite" "Enable"
EndSection
还有一个情况，我用的是TWINVIEW显示模式，在打开桌面效果（立方体上的工作区）以后，主显示器没办法实现立方体效果，但是副显示器却可以。
而且打开桌面效果以后，主显示器上点击菜单弹出速度很迟缓，但是副显示器上却没有这个问题，超级无敌诡异吧？
不知道这个线索是否有用？

让我贴一下我的xorg.conf文件吧，也许更有利于大家集思广益：）

又仔细观察了一下系统监视器，发现一旦光标在输入框中，CPU占用率升高的不是FIREFOX，而是XGL。
为什么？

我现在也可以自己来回答这个问题了：
都是XGL捣的鬼，刚刚把XGL关闭了，UOALA！
整个世界清静了！
感觉系统前所未有的快啊 :D :D
