Since 1.2.13 I'm having graphics issues on the horizon on Windows 10 Edition running in Parallels. The horizon is repeating and keeping surrounding graphics (see screens), moving stars are resulting in lines.

OS: Windows 10 (10.0.16299) in Parallels (13.3.0) on Mac
There are reports of the same issue over at the Parallels forums: https://forum.parallels.com/threads/minecraft-for-windows-10-does-not-work-at-all.342636/
