Very low framerate

[davidebaldini]

The software works as intended, but the framerate is about 0.5 FPS, or one frame every two seconds. Mouse events on the computer client propagate with high delay over the phone. The connection passes thru usb 2.0.

I toggled limitFrameRate=true with no apparent effect.
The CPU load on the phone is low while the screen is shared. Appended is the output of db shell top -m 10.

Perhaps the usb bus is congested?

[Zeik0s]

use https://github.com/Genymobile/scrcpy, it's way better supported and developed actively.

If you still have full access to your device, @Zeik0s's alternative is far way better to use.

It seems this is a common issue on Androids with broken displays, not the fault of this software.

The Genymobile/scrcpy#1285 and referenced issues at scrcpy repo describe the symptoms, which even affect VNC, in my case.

For me, specifically --turn-screen-off feature of scrcpy solved the problem.
