      Possible causes

      This list contains some of the possible causes for this bug. It is not recommended to skip GPU driver updates or similar since it is not guaranteed that this is really causing this bug.

      Workaround

      This comment, this comment and MC-113713 suggest setting the refresh rate to exactly 60 hz fixes this problem.

      Maybe: Comments in this reddit post suggest that resizing the window while the main menu is open before enabling fullscreen mode prevents this issue from happening.
