Is this normal? at DVinfo.net

From time to time I have noticed an odd artifact that appears almost as an inclined dark line 'strobing' across vertcals such as white painted railings or window frames causing a visual 'twitter'. The verticals where this appears are not necessarily those of the finest resolution or minimum pixel width, but are quite narrow; the clip has not been over-exposed and my sharpness setting is at -10. Has anyone else experienced this and is it normal or due to incorrect settings? Is this a characteristic of CMOS, I've never seen it with CCDs.

I've just been playing with a Canon 60d and the problem that I'm experiencing with the EX1 is a little like the moire evident on the 60D, bu by no way as bad. Could it be moire?
