Hello,

When I use the book and quill the edges are white.

I'm not using any texture packs this is pure Minecraft.

The same happens when I am using a texture pack with a transparent GUI - It is opaque.

But sometimes when I boot up Minecraft it suddenly is transparent.

Does anybody know how to fix that or what is the problem?

The version is 1.8.9 but the page didn't let me choose that.
