Screen Tearing with VSync Enabled

In 1.14.3, it appears that enabling vsync doesn't do anything since screen tearing still occurs. I went back to check in 1.14.2 and the issue was not present there.

In macOS, at least on my system, leaving vsync off in any game causes it to have lower, inconsistent frame rate for some reason. This is the behavior that 1.14.3 exhibits even when vsync is enabled, which leads me to believe that the vsync option in 1.14.3 isn't working at all.

Note the generally lowerframe rate in 1.14.3 compared to 1.14.2 in the attached videos. Unfortunately, the screen tearing does not show up in the screen recording, but it is present.
