I login to my minecraft world and all goes fine for the first few seconds but then all solid blocks such as cobblestone & wood go invisible but some blocks such as chests water and lava remain ,often strobing.
I tried to see if it was only on previously generated worlds by generating a new amplified terrain world which went fine for the first 3 minutes or so but then the bug returned...

If I am missing any information please contact me so I can send it to you or if you'd like a video with the showing what the bug is.
