I would be hard pressed to think that there is a significant enough volume displacement from those props to create a Schlieren effect (this is like the waves you see above a road in the middle of the desert). I would have to say the most likely culprits will be the lens, the CMOS (or other sensor) or possible some interference present in the wireless signal.May want to take a look at your user manual to see what settings you can change on the camera itself.

I'm not saying it's a Schlieren effect. I'm saying unbalanced props are causing a vibration. Do a youtube search on the effect.

Or you can mess with CMOS and wiring. Whichever you choose...:D

Can someone please tell me what is causing this problem?  It was the only time I had this issue the whole day...

Thanks in advance.

I believe this is mostly due to flying directly into sunlight. It's an optical effect resulting from the shutter speed, direction you're facing in regards to the sun and gimbal tilt. I've come to realize that if I switch direction slightly, or tilt the gimbal a bite more down, or just not fly against the sun that I won't see these happening.

 

Another option is to fly slower, as you fly faster the drone will be at an angle relative to the sunlight and the props will probably come into the field-of-view and increase this effect your're seeing. That is why you probably won't see the same effect if you're still flying against the sun, but backwards.

I've heard that buying ND filters might help a bit, but really the main advice is not to fly directly facing sunlight.

Hope it helps.

Nice job, totally didn't think of that, yes a set of ND filters and a polarizer are a must for great footage on very bright days. Also making sure that you have set the camera shutter speed to at least double your fps (for the playback) for better results. flying slower will also help great job!
