After looking at that patch, I don't believe it's going to help what you are looking at. They are in a spot where the camera is not even starting up. Ours starts, but the qdoverlay is acting up causing only a 3 line preview to be shown. At this point, I suppose it wouldn't hurt to try it out, but I have a feeling it's all going to come down to the video fixes that RMCC pushed 2 months back.
You're provably right on the patch. I can say that I am no longer having the issue since I switched to the slide lock.
