Mipmap levels seem to have been changed and/or are broken, see screenshots.

This affects the following, but not limited to:

• Tall grass (perhaps all cross-model blocks)
• Glass blocks (not panes)
• All rails
• Cake
• Ladders
• Redstone wire
• Reeds
• Repeaters and comparators
• All doors

Tested using mipmap level two (2).
