Describe the bug

• CameraView version: In September 2323, the main branch
• Camera engine used: camera2
• Device / Android version: Pixel, API 28
• I have read the FAQ page: yes

To Reproduce

private fun initCameraView() {
camera.setLifecycleOwner(this)
camera.addCameraListener(Listener())
}

override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<String?>,
grantResults: IntArray
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
val valid = grantResults.all { it == PackageManager.PERMISSION_GRANTED }
if (valid && !camera.isOpened) {
camera.open()
} else if (!valid) {
ToastUtils.showShort("打开失败，请授予相机权限")
}
}

@natario1 I also found this problem in the operation of the camera in the project, which can basically reach one-tenth of the probability in the scene where the camera is frequently turned on and off. Is there any way to avoid it?
