1, in TIM, QQ, and WeChat applications, the input method does not follow the mouse movement, always at the bottom of the window, not good screenshots, test it yourself, to ensure that everyone has this problem. 2. In applications such as TIM, QQ, and WeChat, there will be a word delay when switching between Chinese and English. This means that you type "sdf" and then press the shift key to switch back to the English state. You type sdf in the input box, and then you can enter the English jj in the English state. At this time, the input box adds jj two letters and becomes "sdfjj", this time you build by shift, theoretically enter "j", it should be in Chinese state, but the input method will first enter a j in the input box, then you switch to Chinese when you input j again In the state. Everyone can experiment, I promise not to be my own problem.
