Everytime I get into the new world I just created, the screen will be light blue, like it is a lag, and the only thing that will be seen is the sky for a while.

But, and most importantly, everytime I break a block, it will disappear, and it won't even be there on the ground (already broken) nor that block will appear in my inventory.

This also happened to me without the texture packs and without shaders (when I was just using the default textures of the game), so this packs are not the responsible for the bugs xd

(Can't send the videos I took because this page doesn't allows videos of even 20 secs xd)
