Command-key is not released after shifting keyboard layout on Mac

[X] I have read the FAQ.
[X] I have searched in existing issues.

Environment

OS: macOS
scrcpy version: dev branch (and before)
installation method: manual build
device model: Sony G8441
Android version: 9

Describe the bug

scrcpy is in focus on Mac
text input field is in focus in scrcpy
switch input language on Mac with command-space, allowing the keyboard layout list to be shown
release the command key to select a keyboard layout

From the point of view of scrcpy, the command key does not get "released", and any keypress after that on the Mac is as if the command key was still held.

For example, if m is pressed when scrcpy is in this state, the menu is shown on the phone, if right arrow is pressed, the screen is rotated, and so on.

This state is kept until one of the command keys is pressed and released by itself.

Notes command key = ⌘ In Preferences -> Keyboard -> Shortcuts -> Input Sources, "Select the previous input source" is set to "⌘Space" and marked as active.

Observation Every time this command-key lock happens, 32 bytes are leaked:
