I hesitated to call this a "bug report" since it isn't really a bug per se.

There is significant latency in keyboard input. I've noticed it getting progressively worse with each release of MartyPC. Now with the latest version it's probably 250ms or something close to it - I haven't tried to measure it, but it's significant enough to add a lot of annoyance to the user experience.

I don't think this is an issue that happens with any particular machine, since it happens no matter where I run MartyPC, but I run Linux Mint on all my systems, so I can't say it's not related to Linux.

I just thought I'd throw this out there to track the "issue", insofar as it is an issue.
