Weird Holes in blocks

I hope this bug gets fixed soon. My computer specs are:

 

Geforce GTX 1050

8GB RAM

500gb Harddrive

Intel Core i5

Please fix 

 

What seems to be happening here is that there is some weird holes in the blocks. They are white lines leading to the void, A couple things happen due to this bug, One being that they can completely stop rendering blocks, because they are way too many of them making the blocks invisible
