Terrible Image Gen 2.0 backgrounds

I've had this happen many times in the new 2.0 generator when trying out prompts from just a few weeks ago describing fully photorealistic outdoor scenes with people in the foreground.

The bokeh effect in the background takes on a weird, horizontally pixelated affect, like the trees in this case were generated as part of video game printed out by a bad inkjet printer.

For reference, this is how I described the background. It had no visual rendering issues in 1.5: "Beyond the field is a small parking lot with a few parked cars. A handful of people are visible in the distance, naturally scaled and not drawing focus from the subject. Trees and greenery surround the area."

Anyone else encountering issues like this?
