Hmmm...any chance this could be an electronic first-curtain shutter issue? You're using a fast lens wide open, and it seems to be oriented horizontally at all times to the frame. Something partially obscuring the frame but moving quickly would appear partially transparent, or cause vignetting, rather than appearing solid. Just an idea on what this could be. I'd say for sure it has nothing to do with white balance, as it's only affecting part of the frame.

I thought of that as well. I turned of the electronic first curtain shutter, but it did not help anything.

But I am guessing that this is due to the sensor and how it processes the information. I tried taking a pic using my phone, and as you can see there is a red band on the screen, that red band is moving from top to bottom.

I have a great gut feel that this is due to using fast lens, with high iso and low battery.
