Hi there, My mouse cursor freezes once every ~30s for about 1~2s. It doesn't happen all the time, but I suspect it might happen because of the usage of postgreSQL, as I've seen 2 other people with the same problem who also used it. I have tested another mouse, the problem persists. I've tried updating mouse/USB drivers as well, nothing helped. My trackpad, however, doesn't stop working at any time. Any ideas? Thanks.
