Seeing it's a system-wide application, it could cause issues.
A couple of ways to find out, that I can think of, would be...
1. Open task manager and see what's running and what is using resources when the stuttering happens (I think this has already been suggested - I haven't read back up the thread to double-check, though).
2. The program looks to be opensource software. If that's the case, it costs nothing to install/uninstall it...
Why not uninstall it run your system without it for a while.... then re-install it in a few days and see what happens.
