Description

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

**Environment**
- OS: Windows 10 21H2
- scrcpy version: 1.22
- installation method: Windows release
- device model: Samsung Galaxy S10e SM-G970F (not rooted)
- Android version: 12

**Describe the bug**
Sometimes, after opening scrcpy to view my Galaxy S10e, when I rotate the screen horizontally, the right half of the screen remains completely black.

This bug is difficult to reproduce because it does not always happen but it is very annoying because the only 2 ways I have found to eliminate the black half is to restart Android (obviously) or to activate "Simulate secondary displays".

I'm not even sure it's caused by scrcpy but I tried for a week never to connect scrcpy to the smartphone and this bug never happened.

Research direction

The report names no source files, tests, or entry points. Start by reproducing the intermittent failure while rotating the Galaxy S10e in landscape, then trace whether the black half is rendered by scrcpy or Android; done means the display remains complete after rotation and the regression is covered by an appropriate test.
