I noticed a particle glitch with the cactus item.
No matter where you place the cactus in your inventory, if your cursor is not in the same section (hotbar/main inventory), or not to the left/above/below the cactus item, the edges of the item will become transparent. If your cursor is to the right this occurs.
It's quite strange really...
You don't have to be in anywhere else but your own inventory to see this.
It's not a serious bug but it's something I felt like pointing out just because.
