Please try a non-snap version.

https://github.com/Genymobile/scrcpy/blob/master/BUILD.md#option-2-use-prebuilt-server

And enable ASAN:

meson x -Db_sanitize=address
ninja -Cx
./run x

I was experiencing problems with Redmi Note 10 Pro with Debian 11, everything was working fine since an update at the beginning of the year. But 2 weeks ago I 've updated to MIUI 13.0.4 and scrcpy now works.

Encountered the same issue when using the latest version2.1 of scrcpy for a Huawei VOG-l29. The following worked for me.

Temporary Workaround 🩹

Downgrade scrcpy version to 1.21.0.

Windows 🪟

If you are using Chocolatey like I am, run the command below in command prompt with admin privileges:

choco install scrcpy --version=1.21.0 --force

Linux 🐧

If you are using apt-get like I am, run the command below in bash terminal:

sudo apt-get update
sudo apt-get install scrcpy=1.21.0

@cardboardcode Please test scrcpy 2.3.1.

Does it work? If not, what is the output in the console?

@rom1v Thank you for the prompt response.

Solution [For Huawei Only] ⭐

Tested with scrcpy 2.3.1. It is working successfully with Huawei VOG-L29. 🥳

Still not sure about the Xiaomi since I don't use Xiaomi devices.
