Yes it was. I used an Amiga with a Commodore monitor and while it was a lot better than any TV or other composite monitor, the interlacing was still noticeable and people's eyes would go wonky staring at that for eight hours a day.
It was awful when compared to the paperwhite monochrome displays of a Mac or the Atari ST. It's frankly one of the things that set the Amiga back in the productivity regard.
