The best way to describe this issue is with photos. The Windows 10 Edition displays text legibly regardless of the viewing angle. The Xbox One version of Minecraft however does not, and has a white aliasing outline around text making it difficult or impossible to read at a distance or at an angle. Also this white outline appears around many other black lines in the game, but don't appear on the Windows 10 Edition. I checked all settings for both systems and they are all the same. I tried playing with the anti-aliasing settings on both to eliminate the white outline on the Xbox One and reproduce it on the PC, but I was able to do neither.
