Extreme motion sickness since the new nether update on iOS

I have been playing Minecraft for years on my iPad without issues, but something about the latest Nether update now causes extreme motion sickness within minutes of playing, such that I can no longer play.   Did something change with the graphics rendering in this update?  Something doesn’t feel right at all.  

Also, the movement of mobs is different - they now look like they are gliding on ice when they move rather than what used to look like normal walking.  For example, iron golems used to clomp around when they walked, now their limbs move very slowly, sorta out of sync with their actual walking and they look instead like they are sliding.
