Android Studio 升级 Canary 3.4 爆炸了..

升级 Canary 3.4 之后在所有需要联想的文本框（代码框、Git Sign-off 框、甚至 Git Commit Message 框）均无法输入字母和数字，以及极少数符号。表现为输入第一个字符后迅速被回退，然后出现两个光标（回退前 & 回退后），并无法输入其它字符。

崩溃了，代码都输不进去让我们用文本编辑器干活啊...

以下是 IDE 反馈的堆栈，不知道是否相关：

一开始怀疑是插件不兼容的问题，所以禁用了所有我装的插件，并 Invalidate cache 了一遍，仍然这样。

不知道 V2er 们有没有遇到类似情况呢？
