Nope that's normal for circular knitting because you're really knitting a spiral. It's usually not a problem unless you're doing garter stitch or changing colors. For garter st, what I do is purl the first round, slip the first st of the next round and switch to knit, knit around including the slipped st, slip the next stitch and purl, including the slipped st on that round, etc until I'm done with the garter section. Then go into stockinette or whatever st pattern. It's not as noticeable that way, and I believe something similar is used for switching colors.
