in my opinion it is not a bug, but a way to make indesign faster.
That’s not a bug; it’s the way it is. How in the world are you measuring .03 seconds?
First, I could have but didn't measure the time. I wanted to indicate a short period of time. I should have said "about a second or less."
I do not recall this behavior in the past. The type is sometimes rendered as smoothly when the screen is moved slowly. Perhaps there is buffering of n number of pixels x or y of the location. Or there is a timing event happening wherein the distance x time matters. This is a code related issue.
The purpose for proxy imaging (showing images in less than full fidelity) is allow users to 'see' positioning quickly. Given the speed of the processors, and specialized rendering engines text should stay smooth. I am displaying on a cinema display. This may be different in retina, or on a PC.
Thank you for reading my comment.
