When I would be playing the game in one of my worlds, like flying around or opening chests, the render distance would go from 12 to 5, without me setting it at 5. With a blink of an eye, you would be able to be everything and then you have the fog all around you. I’ve submitted a report already a few months ago and I later saw it got “fixed,” but it did not get fixed since I’m still seeing it happen. This has been happening for months now. I’m hoping this can get fixed in the next couple of updates since I’m tired of seeing this.
Your previous report was not resolved as Fixed. It was resolved as a Duplicate of MCPE-216671, which was resolved as Works As Intended. Works As Intended means that the described behavior is not a bug.
