Safari youtube fullscreen glitch

Hi,

A while ago I noticed that on random youtube movies I experienced some kind of the glitch when watching in fullscreen mode. What's interesting, this glitch only activates when youtube control panel disappears. If i'm not watching on fullscreen or I'm moving the cursor all the time, screen does not experience any unpleasant interferences.

I waited for some time expecting for safari's update, but until now nothing really has cured the issue.

I'm using Safari Version 11.0.2 (13604.4.7.1.3) on Sierra version 10.13.2 (17C88).

Your support will be much appreciated.

Below I paste a link to the video picturing my problem.

Hey guys, I have just found a fix for that, I had exact same issue on ma 2017 mbp, and what's causing it's the screen scaling feature which you turn on in "my Mac> displays, you have to keep it in normal, not scaled mode -,- I have checked it at apple store, and all Macs there with that scaling mode turned on had the same issue, when you turn the scaling into "default" it only flickers like for half a sec and then plays normal, the same with all three Macs at apple store. It is a problem with graphics compatibility but it seems that all Macs with newer Sierra have that issue. cheers

Yeah, Firefox does not have any issues with displaying video that's problematic for Safari. I think that fresh copy of the OS X is my only hope...

I'm not sure a reinstall will help either.

I'm not 100% certain what is causing the problem.

If you are referring to the somewhat jerky scrolling, that is probably normal. The Safe Mode runs a little slower.

The same problem only started happening on 10.13.4 (17E199) with MacBook Air 11 (early 2015) and only safari glitches on youtube fullscreen videos and only 720p.

Yeah, mine has always been on the default setting and I still have this issue.

Also it cured my Netflix, before I was experiencing mili-sec green artifacts, and random flickering at first 15 seconds of playing

I have the same issue with the 2015 11' MacBook Air running the latest High Sierra update. I end up watching all my fullscreen web content on Firefox for that reason, still haven't figured it out.
