I have been experiencing this problem for a while in HaxeFlixel and recently i tested OpenFL to see if the problem would appear there also.
Turns out the exact same problem occurs when doing scrolling in pure OpenFl.
This affects neko and cpp targets as far as i know.
I posted a demo showing the problem here: https://github.com/Tiago-Ling/JitterDemo
There are two projects there, one for HaxeFlixel and the other OpenFl.
I wonder if am i doing something wrong or is this a problem in the core rendering system?
If this is indeed a bug in OpenFL it is a very serious one - any scrolling, even in very low speeds presents this “blurring” in a very perceivable way.
Is anyone having the same problem, either in the demo above or in your own projects?
