Mojave 10.14.3 - Safari Youtube Fullscreen Problem

[DaniloDelTufo]

Hello there, I'm experiencing a problem with Safari and Youtube. When entering in full screen mode, the video appears at the left of screen and the right side is black. The problem is the same described here https://discussions.apple.com/thread/7371819) and here: (

). I've tried everything, re-installing the OSX, disabling extension safari, safe mode, mission control, general "when mouse scrolling" etc...I've contacted Apple they said it's problem that needs to be addressed by them with next update, but frankly I didn't find any recent discussion about the problem in REDDIT for example or other forums. Have you experienced the same problem, and is there some fix? I've tried everything expect format and re-installing, but Apple said that probably the problem will appear again also with format. Please help me! Thanks!

It's been doing this since the Mojave beta and they still haven't fixed it. Nothing to worry about.

Thanks, NastyNatex! I was worried about it and you saved me a format and re-installing OSX.

Changing scrollbar visibility to "while scrolling" fixes this bug. (System preferences → General)

I've already tried, but it doesn't work. Have you some other suggestion?

It worked for me (without even restarting nor logging off) No more ideas, though...

Thanks, before starting the thread I've searched on the web a lot of solutions without a clue, and tried every solution available on apple support forum and others. The only thing that I have not tried is formatting and reinstalling everything, I've just re-installed the OS, without any success. I hope that Apple will fix it soon with some update, however the Apple support told me it's not only my iMac that got the problem, so there's a hope for a general fix with the next Mojave update.
