Update by rplatham:
Confirmed on Samsung Galaxy S4 SGH-I337M Android 5.0.1, MCPE 22.214.171.124.
Steps to Reproduce: Create new creative flat single player world, using tp command to move to these coordinates, build end portals and observe as follows:
- 254,6,0 (end portal has stretched pixels in N/S direction)
- 0,6,254 (end portal has stretched pixels in E/W direction)
- 0,254,0 (end porta is fine, no stretched pixels)
This bug does not affect my Samsung Galaxy S6 SM-G920W8 Android 6.0.1 (consensus seems to be that this bug does not affect Android 6)
The end portal texture is really weird.
Device: DL Tablet 3405
PS: It has a Intel Atom processor.
