Safari displaying content from previously watched video Netflix

I have two MacBooks - Air and Pro and only Pro is affected probably because of retina (high-resolution).

My Mac: MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)

Graphics: Intel Iris Plus Graphics 640 1536 MB

System: 10.14 (18A391)

Step to replicate (with clean system)

1. Open Safari

2. Go to youtube.com watch any full hd/ 4k content

3. Go to Netflix

4. Netflix will 'flicker' from time to time showing the frame from a previously watched content.

To solve this issue I have tried to wipe out my hard drive and reinstall the system. I have also tried to use Safari Technology Preview and it is also affected. Not sure if there is a fix other than manually wiping the cache.

Any ideas?

Screenshots are below:

Here you can see, that netflix is working as expected.

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/com.apple.Safari/Cache.db and move it to the trash.

Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.
