Random Left Click Inputs

- [*] I have read the [FAQ](https://github.com/Genymobile/scrcpy/blob/master/FAQ.md).
- [*] I have searched in existing [issues](https://github.com/Genymobile/scrcpy/issues).

**Environment**
- OS: [Windows 10]
- scrcpy version: [2.0]
- installation method: [Windows release]
- device model: HUAWEI Y9 Prime 2019 (STK-L22)
- Android version: [10]

**Bug Description**
Device is connected properly via USB in OTG Mode, and the mouse and keyboard are very responsive. There's just one problem on the mouse input; it sometimes executes a left click even though I didn't left-click on the mouse.
