Weird lines in the background

Have anyone else had these weird lines in the background? I am shooting with a 7d mk1 and a Tamron 150-600mm G1
In the beginning when i shot with this setup I had no issues, but then sol New updates came out, I guess that was the problem. But then I went back to an older version and had the same problem. Any ideas?

I don’t see anything unusual. I see grass in the blurred background, the bokeh that is characteristic of your lens, and a little bit of posterization in the bokeh (which can be adjusted using DeepPRIME settings, local adjustments, or another software such as Topaz). Can you be more specific about what you think is wrong?


I can upload a crop of the photo, because it is absolutely terrible😏
