Jerky mouse over tcp (--no-video --no-audio)

## Environment

- MacOS
- scrcpy 3.3.4
- brew
- Samsung Galaxy Tab S11
- 16 OneUI 8.0

## Describe the bug

Apologies for yet another "slowness over tcp" ticket, but I hadn't seen this particular issue discussed yet. I'm attempting to control my android device with my mac keyboard using the following command:

```scrcpy --no-video --no-audio -K -M -e```

This works fine when I do it over usb (`-d`), but when I try it over tcp (`-e`), I get very jerky mouse movement. I know there there is a limit to the bandwidth available, but since I'm not sending any video data over the pipe at all, I would think there would be enough bandwidth for smooth mouse movement. (Perhaps I'm wrong?).

Thanks so much for all your work on this software!

Start by reproducing the reported command, `scrcpy --no-video --no-audio -K -M -e`, and compare mouse movement over TCP with USB using `-d`. Investigate why mouse input is jerky only over TCP; done means smooth mouse control in the reported no-video, no-audio TCP configuration.
