Video inclined in fullscreen

I have a problem with my MacBook Air (11-inch, Early 2015) since macOS 10.13.4 update. When playing a video in fullscreen, it shows inclined, like two pieces side by side. It happens in iTunes (not in QuickTime X) and Safari. There's no problem when an object overlays the video, like scrolling tool at the bottom, subtitles or system sound level. In YouTube in Safari, the same thing happen. Videos play correctly when an icon appears in the right corner or options at the bottom. The same videos play well in Chrome and Firefox (maybe Chrome and Firefox don't use h.264 videos).

This is a picture of my screen. I added a red line where the video is cut in half. Is it a known issue?

MacBook Air, macOS High Sierra (10.13.4), null

Same problem here on MacBook Air 11'' running High Sierra 10.13.6.

Workaround for me was to change display resolution to 1280x720.

Fullscreen video (iTunes/Netflix/Youtube) back to normal after change.

Hope it works for others.

Yeah, seems to be a lot of us having this issue after the update and to no surprise Apple doesn't want to address it.

Thanks for that little 'workaround' Jody, although the resolution doesn't look all that too different, it has fixed the issue so thanks a lot!

Has anyone found a resolution to this issue yet? I rolled back to Sierra and the issue doesn't happen anymore. If anyone is interested in another solution.
