Bug:
When doing a mixed slabs with slabs with slabs from the mod Minegate, the block becomes invisible, and if you try to mine it on survival the game crashes. When you load back in, part of the chunk where the block is placed is invisible now, and trying to mine the block crashes it again. Disabling the mods fixes it and doesn't corrupt the save (as far as I could see).
Didn't try with slabs from other mods though.
Edit: Just tried with "More slabs stairs and walls" mod slabs and didn't crash. The only issue was that when combining a stained glass slab with other slab it would become a solid color, and if you put a glass slab (not tainted) first and then another one above the glass slab, terrain wouldn't render if you see across that glass slab.
