Describe the bug

Create a virtual display with scrcpy 3.0:

./scrcpy --new-display=1920x1080 --start-app com.android.chrome

At first, touch control with mouse works, but when the phone screen dims after a while, the virtual display can't be controled by mouse, but keyboard works.

Console output is:

./scrcpy --new-display=1920x1080 --start-app com.android.chrome --turn-screen-off

It depends on the device.

On a Pixel 8, I can open a virtual display without even turning the physical screen on.

As a workaround, you can probably use the new --screen-off-timeout option (or the old --stay-awake if plugged on USB) and turn the physical screen off with #5522.

Does it also happen with main screen mirroring with --turn-screen-off?

I tested this on my setup (Windows 11 and a Xiaomi phone running Android 13 connected via USB) with main screen mirroring. When the phone screen times out, the lock screen appears, and the mouse still works. However, I can't unlock the phone because the pattern unlock screen doesn’t appear, and the under-screen fingerprint reader isn’t functional in this mode. The mouse issue arises only with the virtual screen after the main screen times out, not with the mirrored main screen. The keyboard continues to function normally in both modes.

I was recently testing the virtual display on my pixel 7, it works well and surprisingly no issues if you started the display and continuously using the display with the device screen off. However, if you try to switch application on your computer, after coming back to the window, the screen won't respond on your mouse clicks. Keyboard still works though.
