Description

Describe the bug

Mouse latency its about 100-120ms laggy wich makes any game unplayable, only maybe desktop use is tolerable.
I´ve tryed everything but nothing fixes this problem.
Maybe using the Android cursor is could be a solution. At least fow desktop usage and real time strategy games.
I can make the Android cursor apear by windowing the Moonlight app on my tablet with Android 13. That mitigates the latency but makes the screen so small that is useless.

Research direction

No source file, test, log, or entry point is named. Start by reproducing the reported 100–120 ms latency on Android 13 with the Lenovo Tab 13, then compare the behavior across desktop use and games; done would require identifying the input path responsible and verifying that latency is reduced.
