Just installed a fresh new Forge server version 1.8-11.14.4.1563 on my linux server. All clean, no additional mods. I used the same installer (jar version) to also install my client (on Windows 7-64bit).
Everything seems to work OK, until I teleport to a region with high coordinates, such as:
/tp myname 20000000 100 20000000
The world now looks severly messed up!

Being a software developer myself, I did some research, and it appears the bug has appeared somewhere between build 1.8-11.14.3.1450 and build 1563. Check out these tests:
Server b1563, client b1563: world messed up
Server b1450, client b1563: world messed up
Server b1450, client b1450: world OK
Server b1563, client b1450: world OK
Server is running: OpenJDK 64-Bit Server VM, version 1.7.0_51
Client is running: Java SE Runtime Environment (build 1.8.0_40-b26)
Let me know if you need any more information. I can reproduce this at any time.
Kind regards,
