occasionally during usage, the input for touchpad gets real slow. I think the issue is multi-threaded input in the face of multiple programs requesting threads. It might be possible to slightly mitigate by running both input checks as tasks in a single thread when there is likely recognizable bottle neck while also recording some type of timestamp of last mouse position to remove the race condition of the deprioritized single task thread.

Steps for reproducing this issue:

  1. use firefox a while without a keyboard and multiple tabs open.
