Evere since upgrading to InDesign CS6, my Display Performance seems to render visuals erraticaly. As a default I keep everything set to "Typical" (under View > Display Performance). I have been noticing that some pages will render my placed graphics as though my DP is set to "Fast" (by showing solid grey boxes). I've also noticed when I change my setting to "High Quality", some of the pages will still render as "Fast" and some as "Typical". This is happening to different pages in the same document, but also happening in different (not all) of my documents.
I'm wondering if anyone else is having a smiliar problem?
That's certainly not typical. One possibility is that object level dispaly settings are enabled, and set to lower quailty for some reason on these images. Another possibility is that your prefs are hosed. See Replace Your Preferences
