This really does need to be fixed. It causes a lot of waste in rerunning materials and wasted repair time.
Most every designer on Earth uses high-resolution JPGs for color images. Which means that setting preflight profiles to alert you for the problem can save you much of the material cost, but alert on near every job. And that means lots and lots of wasted time.
I'm not a software developer, so I can't venture the guess on what causes the problem. But it needs to be found, and it needs to be addressed and corrected. This is a big deal.
