Missing input on Unity search bar when using gcin（使用gcin輸入法時輸入搜索字串於Unity會漏字））

*My native language is Chinese, the English description may no be accurate enough

Remake steps
重現步驟：
1.First activate gcin once.
先啟動gcin至少一次。
2.Input English characters on Unity's search bar.
 於Unity的搜索列上輸入英文。

***This bug can be remade on multiple machines running 11.10***

What you expected to happen:
input appear on the search bar normally.
輸入字串正常地出現再搜索列上。

What happened instead:
About half input disappeared
約有一半的輸入會遺失

Also:
gcin couldn't input Chinese on Unity TOTALLY.....
