Sensitive interface black screen

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

**ENVIRONMENT**.
- Operating system: [Windows].
- scrcpy version: [2.3.1].
- Installation method: [Windows version USB connection]
- Device Model
- Android Version [Xiaomi HyperOS Android14]

**Error in description**
2 main problems:

1.Occasionally the screen becomes blurred during connection operation.

2. When operating the software interface which needs to input password or verification code, the corresponding software interface will become black screen state, but you can click on the operation, the cell phone side is displayed normally, just the computer side is black screen state, is it the HyperOS security policy?

Start by reproducing both reported behaviors with scrcpy 2.3.1 over a Windows USB connection on Xiaomi HyperOS Android 14. Compare ordinary screens with password or verification-code screens, then determine whether the blur and computer-side black screen are reproducible and whether they indicate an Android security-policy limitation; no source file or test is named in the report.
