So this is what’s happening:
(Image of a single screenshot of the game while paused showing the platforms the player is running on. Text has been added in post to clarify problem)
While the player is moving, some 2d sprites are becoming blurred (even while the game is paused). I have disabled motion blur in the post process volume, the camera, and in the project settings.
Yet it is still getting blurred.
What else could be causing this blurring effect?
