Shooting with EOS R in photo mode during night introduces black lines in some pics.

Please find the pic attached. EOS R seems to introduce black lines when shot during the night under artificial light sources. Holding down the shutter button, I can see that black patch moving across the screen in EVF and in live view. Any help with this is really appreciated. I thought it's a defective unit that I had received and had to return it. But, it's the same exact problem with my second EOS R as well. I shot with the same settings on my 6d Mark ii DSLR and it doesn't have it.

Thanks in advance for any help with this.

Thank you so much. That resolved the issue. I though I enabled it, but have been shooting with it disabled all the while. Thanks again 🙂
