I agree with Mt Spokane. It looks like it could be some physical debris, or a bug or something physically inside the camera or lens.
I assume you've tried several lenses, also cleaned the sensor?
Providing a real image instead of a screenshot would definitely be a good start.
I have two lens for this camera, and notice it on lens, and check the other and now notice it a bit more.
The best way you help yourself is to walk outside , take some photos and post them here so we could look at it. Multiple photos to see if it actually moves or not. The example so far and your comments are not helping me understand how the issues arises and how it impacts. We'd all be delighted to help if you could give good examples and clear explanations. Please ensure the back of your lens is clean.
Sorry, i finding it a bit hard to explain this by text, I took a load of photos on Sunday and upload some tonight and I will check the back of both lens are clean.
