fullscreen glitch with Netflix on subtitles in Safari

Did you manage to find a solution? Same here MacBook Pro 15" late 2016.

Video "flickers horizontally"after subtitle or media control dissapears in Netflix or Youtube fullscreen in safari.

Only happens when integrated GPU is used, on dedicated everything is fine.

Try checking you Display Settings for scaling. I had my scaling set to "More Space" and was getting the same issue. Really annoying. Set it to "Default" and Netflix started maintaining its aspect ratio in the normal fashion during subtitle generation.

You appear to be correct, checking to "native" resolution does appears to resolve the issue.

However, for MacBook Pro 2016 and newer, the "default" resolution isn't the native one. So it requires to pick scaled "looks like 1440x900"...

not really a fix, just workaround, but interesting.

I already tried re-installing MS Silverlight,

MSSilverLight has been abandoned, and is no longer appropriate for use with these and other services like them.

Same problem here, happens also sometimes in YT... Did someone found a solution ?

I have the same problem. it´s safari. it´s buggy for a looooooooooong time. no fix in sight. just use another browser.
